This is the wrong mailing list.  This mailing list is for people
develping gcc itself.  For questions about using gcc, please use
gcc-help@gcc.gnu.org.  Please send any followup questions to gcc-help
or to some other appropriate mailing list.  Thanks.


getopt is part of the C library.  gcc does not provide a C library.
gcc includes copies of getopt_long for internal use.  That code is
used by gcc itself, not by programs which use gcc.

You can find copies of getopt_long for your program in the gnulib
package on savannah.gnu.org.  Please note the licensing requirements
shown there.
