            Bug ID: 125503
           Summary: [17 Regression] libgcobol/m4/autoconf.m4 file is
                    missing, fails autoreconf
           Product: gcc
           Version: 17.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: cobol
          Assignee: unassigned at gcc dot gnu.org
          Reporter: slyfox at gcc dot gnu.org
  Target Milestone: ---

Noticed build failure on `master` in one of my environments that reconfigure
`gcc` as:

       Running autoreconf in /build/source/libgcobol
       m4:aclocal.m4:1170: cannot open `m4/autoconf.m4': No such file or
directory
       autom4te: m4 failed with exit status: 1

I think libgcobol/m4/autoconf.m4 should be in version control:

$ find -name autoconf.m4
./libphobos/m4/autoconf.m4
./libga68/m4/autoconf.m4

$ git grep m4/autoconf.m4 | grep -F .m4:
libga68/acinclude.m4:m4_include([m4/autoconf.m4])
libgcobol/aclocal.m4:m4_include([m4/autoconf.m4])
libphobos/acinclude.m4:m4_include([m4/autoconf.m4])

Should libgcobol follow the other users?

I suspect r17-986-gcc432cc1fc03df as a culprit.
