            Bug ID: 103476
           Summary: --enable-maintainer-mode fails with "invalid
                    separator" in libgfortran on POWER
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: blocker
          Priority: P3
         Component: target

powerpc64le-unknown-linux-gnu/libgfortran/Makefile

Trying to work on the power-ieee128 branch has hit a snag:  It is
currently impossible to use --enable-maintainer-mode on the virtual
machine set aside for it.

This also occurs for a current trunk, so it is independent of any
changes there.

The error is strange:

make[4]: Entering directory
'/home/ubuntu/tkoenig/trunk-bin/powerpc64le-unknown-linux-gnu/libquadmath'

Also, looking at the Makefile in question at line 7771 has this:

$(i_matmulavx128_c): m4/matmulavx128.m4 m4/matmul_internal.m4 $(I_M4_DEPS)
        $(M4) -Dfile=$@ -I$(srcdir)/m4 matmulavx128.m4 > $@

Here are the relevant versions for maintainer mode:

I also have no idea what "missing separator" means in that context,
the line looks legit.

OK, that's it.

It also seems that I configured the wrong binary branch.

Thanks for the help!

Best regards
