           Summary: Unresolved reference to module getopt
           Product: gcc
           Version: 12.0

Mechanical patch

The next build error from the devel/modula-2 branch occured like this:

/vol/gcc/src/git/modula-2/libgm2/libm2pim/../../gcc/m2/gm2-libs/GetOpt.mod:213:11:
error: the file containing the definition module ‘getopt’ cannot be found
  213 | END GetOpt.
      |           ^
make[5]: *** [Makefile:950: GetOpt.lo] Error 1
make[5]: Leaving directory
'/var/gcc/gcc-12.0.0-20210708/11.4-gm2/i386-pc-solaris2.11/libgm2/libm2pim'

The module has been renamed to cgetopt since.  I'm attaching a patch for
gcc/m2/gm2-libs/GetOpt.mod for correct this.

While the Makefile.am's reflect the new name, the corresponding Makefile.in's
haven't been regenerated.

On top of that, the current files have been generated with automake 1.16.1,
while gcc requires automake 1.15.1 as documented in install.text.  To get
around
this, one first needs to regenerate aclocal.m4 with aclocal 1.15.1 in order to
be able rerun automake.
