      -print-file-name=<lib>   Display the full path to library <lib>
      -print-prog-name=<prog>  Display the full path to compiler component <prog>
      -print-multiarch         Display the target's normalized GNU triplet, used as
                               a component in the library path
      -print-multi-directory   Display the root directory for versions of libgcc

      -print-sysroot           Display the target libraries directory
      -print-sysroot-headers-suffix Display the sysroot suffix used to find headers
      -Wa,<options>            Pass comma-separated <options> on to the assembler
      -Wp,<options>            Pass comma-separated <options> on to the preprocessor

      -no-canonical-prefixes   Do not canonicalize paths when building relative
                               prefixes to other gcc components
      -pipe                    Use pipes rather than intermediate files
      -time                    Time the execution of each subprocess
      -specs=<file>            Override built-in specs with the contents of <file>
      -std=<standard>          Assume that the input sources are for <standard>
      --sysroot=<directory>    Use <directory> as the root directory for headers
                               and libraries
      -B <directory>           Add <directory> to the compiler's search paths
      -v                       Display the programs invoked by the compiler
      -###                     Like -v but options quoted and commands not executed
      -E                       Preprocess only; do not compile, assemble or link
      -S                       Compile only; do not assemble or link
      -c                       Compile and assemble, but do not link
      -o <file>                Place the output into <file>
      -pie                     Create a position independent executable
      -shared                  Create a shared library
      -x <language>            Specify the language of the following input files
                               Permissible languages include: c c++ assembler none
                               'none' means revert to the default behavior of
                               guessing the language based on the file's extension
    
    Options starting with -g, -f, -m, -O, -W, or --param are automatically
     passed on to the various sub-processes invoked by g++.  In order to pass
     other options on to these processes the -W<letter> options must be used.
