Possible #if / #endif blocks are compile options. There is no mechanism yet on BoxMatrix to detect which of these are set per model.

set [-abefhkmnptuvxBCHP] [-o option-name] [--] [arg ...]

Set or unset values of shell options and positional parameters.

Change the value of shell attributes and positional parameters, or
display the names and values of shell variables.

Options:
  -a  Mark variables which are modified or created for export.
  -b  Notify of job termination immediately.
  -e  Exit immediately if a command exits with a non-zero status.
  -f  Disable file name generation (globbing).
  -h  Remember the location of commands as they are looked up.
  -k  All assignment arguments are placed in the environment for a
      command, not just those that precede the command name.
  -m  Job control is enabled.
  -n  Read commands but do not execute them.
  -o option-name
      Set the variable corresponding to option-name:
          allexport    same as -a
          braceexpand  same as -B
#if defined (READLINE)
          emacs        use an emacs-style line editing interface

#endif
          ignoreeof    the shell will not exit upon reading EOF
          interactive-comments
                       allow comments to appear in interactive commands
          keyword      same as -k
#if defined (JOB_CONTROL)
          monitor      same as -m
#endif
          noclobber    same as -C

          noglob       same as -f
          nolog        currently accepted but ignored
#if defined (JOB_CONTROL)
          notify       same as -b
#endif
          nounset      same as -u
          onecmd       same as -t
          physical     same as -P
          pipefail     the return value of a pipeline is the status of
                       the last command to exit with a non-zero status,
                       or zero if no command exited with a non-zero status
          posix        change the behavior of bash where the default
                       operation differs from the Posix standard to
                       match the standard
          privileged   same as -p
          verbose      same as -v
#if defined (READLINE)
          vi           use a vi-style line editing interface
#endif /* READLINE */
          xtrace       same as -x
  -p  Turned on whenever the real and effective user ids do not match.
      Disables processing of the $ENV file and importing of shell
      functions.  Turning this option off causes the effective uid and
      gid to be set to the real uid and gid.
  -t  Exit after reading and executing one command.
  -u  Treat unset variables as an error when substituting.
  -v  Print shell input lines as they are read.
  -x  Print commands and their arguments as they are executed.
#if defined (BRACE_EXPANSION)
  -B  the shell will perform brace expansion
#endif /* BRACE_EXPANSION */
  -C  If set, disallow existing regular files to be overwritten
      by redirection of output.
  -E  If set, the ERR trap is inherited by shell functions.
#if defined (BANG_HISTORY)
  -H  Enable ! style history substitution.  This flag is on
      by default when the shell is interactive.
#endif /* BANG_HISTORY */
  -P  If set, do not resolve symbolic links when executing commands
      such as cd which change the current directory.
  -T  If set, the DEBUG and RETURN traps are inherited by shell functions.
  --  Assign any remaining arguments to the positional parameters.
      If there are no remaining arguments, the positional parameters
      are unset.
  -   Assign any remaining arguments to the positional parameters.
      The -x and -v options are turned off.

Using + rather than - causes these flags to be turned off.  The
flags can also be used upon invocation of the shell.  The current
set of flags may be found in $-.  The remaining n ARGs are positional
parameters and are assigned, in order, to $1, $2, .. $n.  If no
ARGs are given, all shell variables are printed.

Exit Status:
Returns success unless an invalid option is given.

Excerpt from:   bashref.info   >>   The Set Builtin   >>   set command

set [--abefhkmnptuvxBCEHPT] [-o OPTION-NAME] [ARGUMENT ...]
     set [+abefhkmnptuvxBCEHPT] [+o OPTION-NAME] [ARGUMENT ...]

If no options or arguments are supplied, 'set' displays the names
and values of all shell variables and functions, sorted according
to the current locale, in a format that may be reused as input for
setting or resetting the currently-set variables.  Read-only
variables cannot be reset.  In POSIX mode, only shell variables are
listed.

When options are supplied, they set or unset shell attributes.
Options, if specified, have the following meanings:

-a
     Each variable or function that is created or modified is given
     the export attribute and marked for export to the environment
     of subsequent commands.

-b
     Cause the status of terminated background jobs to be reported
     immediately, rather than before printing the next primary
     prompt.

-e
     Exit immediately if a pipeline (*note Pipelines::), which may
     consist of a single simple command (*note Simple Commands::),
     a list (*note Lists::), or a compound command (*note Compound
     Commands::) returns a non-zero status.  The shell does not
     exit if the command that fails is part of the command list
     immediately following a 'while' or 'until' keyword, part of
     the test in an 'if' statement, part of any command executed in
     a '&&' or '||' list except the command following the final
     '&&' or '||', any command in a pipeline but the last, or if
     the command's return status is being inverted with '!'.  If a
     compound command other than a subshell returns a non-zero
     status because a command failed while '-e' was being ignored,
     the shell does not exit.  A trap on 'ERR', if set, is executed
     before the shell exits.

     This option applies to the shell environment and each subshell
     environment separately (*note Command Execution
     Environment::), and may cause subshells to exit before
     executing all the commands in the subshell.

     If a compound command or shell function executes in a context
     where '-e' is being ignored, none of the commands executed
     within the compound command or function body will be affected
     by the '-e' setting, even if '-e' is set and a command returns
     a failure status.  If a compound command or shell function
     sets '-e' while executing in a context where '-e' is ignored,
     that setting will not have any effect until the compound
     command or the command containing the function call completes.

-f
     Disable filename expansion (globbing).

-h
     Locate and remember (hash) commands as they are looked up for
     execution.  This option is enabled by default.

-k
     All arguments in the form of assignment statements are placed
     in the environment for a command, not just those that precede
     the command name.

-m
     Job control is enabled (*note Job Control::).  All processes
     run in a separate process group.  When a background job
     completes, the shell prints a line containing its exit status.

-n
     Read commands but do not execute them.  This may be used to
     check a script for syntax errors.  This option is ignored by
     interactive shells.

-o OPTION-NAME

     Set the option corresponding to OPTION-NAME:

     'allexport'
          Same as '-a'.

     'braceexpand'
          Same as '-B'.

     'emacs'
          Use an 'emacs'-style line editing interface (*note
          Command Line Editing::).  This also affects the editing
          interface used for 'read -e'.

     'errexit'
          Same as '-e'.

     'errtrace'
          Same as '-E'.

     'functrace'
          Same as '-T'.

     'hashall'
          Same as '-h'.

     'histexpand'
          Same as '-H'.

     'history'
          Enable command history, as described in *note Bash
          History Facilities::.  This option is on by default in
          interactive shells.

     'ignoreeof'
          An interactive shell will not exit upon reading EOF.

     'keyword'
          Same as '-k'.

     'monitor'
          Same as '-m'.

     'noclobber'
          Same as '-C'.

     'noexec'
          Same as '-n'.

     'noglob'
          Same as '-f'.

     'nolog'
          Currently ignored.

     'notify'
          Same as '-b'.

     'nounset'
          Same as '-u'.

     'onecmd'
          Same as '-t'.

     'physical'
          Same as '-P'.

     'pipefail'
          If set, the return value of a pipeline is the value of
          the last (rightmost) command to exit with a non-zero
          status, or zero if all commands in the pipeline exit
          successfully.  This option is disabled by default.

     'posix'
          Change the behavior of Bash where the default operation
          differs from the POSIX standard to match the standard
          (*note Bash POSIX Mode::).  This is intended to make Bash
          behave as a strict superset of that standard.

     'privileged'
          Same as '-p'.

     'verbose'
          Same as '-v'.

     'vi'
          Use a 'vi'-style line editing interface.  This also
          affects the editing interface used for 'read -e'.

     'xtrace'
          Same as '-x'.

-p
     Turn on privileged mode.  In this mode, the '$BASH_ENV' and
     '$ENV' files are not processed, shell functions are not
     inherited from the environment, and the 'SHELLOPTS',
     'BASHOPTS', 'CDPATH' and 'GLOBIGNORE' variables, if they
     appear in the environment, are ignored.  If the shell is
     started with the effective user (group) id not equal to the
     real user (group) id, and the '-p' option is not supplied,
     these actions are taken and the effective user id is set to
     the real user id.  If the '-p' option is supplied at startup,
     the effective user id is not reset.  Turning this option off
     causes the effective user and group ids to be set to the real
     user and group ids.

-t
     Exit after reading and executing one command.

-u
     Treat unset variables and parameters other than the special
     parameters '@' or '*' as an error when performing parameter
     expansion.  An error message will be written to the standard
     error, and a non-interactive shell will exit.

-v
     Print shell input lines as they are read.

-x
     Print a trace of simple commands, 'for' commands, 'case'
     commands, 'select' commands, and arithmetic 'for' commands and
     their arguments or associated word lists after they are
     expanded and before they are executed.  The value of the 'PS4'
     variable is expanded and the resultant value is printed before
     the command and its expanded arguments.

-B
     The shell will perform brace expansion (*note Brace
     Expansion::).  This option is on by default.

-C
     Prevent output redirection using '>', '>&', and '<>' from
     overwriting existing files.

-E
     If set, any trap on 'ERR' is inherited by shell functions,
     command substitutions, and commands executed in a subshell
     environment.  The 'ERR' trap is normally not inherited in such
     cases.

-H
     Enable '!' style history substitution (*note History
     Interaction::).  This option is on by default for interactive
     shells.

-P
     If set, do not resolve symbolic links when performing commands
     such as 'cd' which change the current directory.  The physical
     directory is used instead.  By default, Bash follows the
     logical chain of directories when performing commands which
     change the current directory.

     For example, if '/usr/sys' is a symbolic link to
     '/usr/local/sys' then:
          $ cd /usr/sys; echo $PWD
          /usr/sys
          $ cd ..; pwd
          /usr

     If 'set -P' is on, then:
          $ cd /usr/sys; echo $PWD
          /usr/local/sys
          $ cd ..; pwd
          /usr/local

-T
     If set, any trap on 'DEBUG' and 'RETURN' are inherited by
     shell functions, command substitutions, and commands executed
     in a subshell environment.  The 'DEBUG' and 'RETURN' traps are
     normally not inherited in such cases.

--
     If no arguments follow this option, then the positional
     parameters are unset.  Otherwise, the positional parameters
     are set to the ARGUMENTS, even if some of them begin with a
     '-'.

-
     Signal the end of options, cause all remaining ARGUMENTS to be
     assigned to the positional parameters.  The '-x' and '-v'
     options are turned off.  If there are no arguments, the
     positional parameters remain unchanged.

Using '+' rather than '-' causes these options to be turned off.
The options can also be used upon invocation of the shell.  The
current set of options may be found in '$-'.

The remaining N ARGUMENTS are positional parameters and are
assigned, in order, to '$1', '$2', ... '$N'.  The special parameter
'#' is set to N.

The return status is always zero unless an invalid option is
supplied.
