This patch uses the libiberty getopt long functions (wrapped up inside libgm2/libm2pim/cgetopt.cc) and only enables this implementation if libgm2/configure.ac detects no getopt_long and friends on the target. gcc/m2/ChangeLog: PR modula2/111530 * gm2-libs-ch/cgetopt.c (cgetopt_cgetopt_long): Re-format. (cgetopt_cgetopt_long_only): Re-format. (cgetopt_SetOption): Re-format and assign flag to NULL if name is also NULL. * gm2-libs/GetOpt.def (AddLongOption): Add index parameter and change flag to be a VAR parameter rather than a pointer. (GetOptLong): Re-format. (GetOpt): Correct comment. * gm2-libs/GetOpt.mod: Re-write to rely on cgetopt rather than implement long option creation in GetOpt. * gm2-libs/cgetopt.def (SetOption): has_arg type is INTEGER. libgm2/ChangeLog: PR modula2/111530 * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * config.h.in: Regenerate. * configure: Regenerate. * configure.ac (AC_CHECK_HEADERS): Include getopt.h. (GM2_CHECK_LIB): getopt_long check. (GM2_CHECK_LIB): getopt_long_only check. * libm2cor/Makefile.in: Regenerate. * libm2iso/Makefile.in: Regenerate. * libm2log/Makefile.in: Regenerate. * libm2min/Makefile.in: Regenerate. * libm2pim/Makefile.in: Regenerate. * libm2pim/cgetopt.cc: Re-write using conditional on configure and long function code from libiberty/getopt.c. gcc/testsuite/ChangeLog: PR modula2/111530 * gm2/pimlib/run/pass/testgetopt.mod: New test.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
