A bit of repetition first:
• GCC 15 compilation started with exactly naming /opt/local/bin/gmake
as tool to build with.
• Build process stopped in
.../gcc15-678e8911/work/build/powerpc-apple-darwin9/libgcc when the symlink
"md-unwind-def.h" was missing for source file
.../gcc15-678e8911/work/gcc-15.2.0/libgcc/unwind-dw2.c.
• Only three symlinks (out of five) to C header files were created.
• I created manually the two missing symlinks.
• When the build process continued, GMake created another symlink from
the same macro, LIBGCC_LINKS, that points to a C source file.
One day or such later in next build stage the same error happened again:
checking for strub support... yes

Since configure had already produced a Makefile to build in libgcc I removed
the three created symlinks + libgcc_tm.stamp and libgcc_tm.h. Then I invoked
"env LANG=C /opt/local/bin/gmake -d" in this directory. On the almost 10,000
lines of GMake output the missing two symlinks to C header files, sfp-machine.h
and md-unwind-def.h, are *never* mentioned.
I cannot find the cause why GMake (GNU Make 4.4.1, Built for
powerpc-apple-darwin9.8.0) is neglecting the two symlinks, they're not
mentioned in debug output, kind of invisible in Makefile, do not need to exist
(yet?). Could it be that sfp-machine.h and md-unwind-def.h need to be mentioned
as dependants in some other Makefile? Then the question arises: Why only here?
I started building GCC 15 on my up-to-day Mac with an intel CPU where all six
symlinks where built at once:

The log file of its debug output is available, the Makefile too and also its
corresponding Makefile.in.
