I renamed - as you suggested - append_glyph to store_next_glyph and
produce_stretch_glyph to generate_stretch_glyph in xdisp.c and tried to
build with the original cc and gcc.
The linker error is gone for both compilers. With gcc
make bootstrap and make install succeeded. emacs could
be started.
cc fails with this error in lib-src:
cc -DHAVE_CONFIG_H -I. -I../src -I/T/tools/unix/build/emacs/emacs/lib-src
-I/T/tools/unix/build/emacs/emacs/lib-src/../src -g
/T/tools/unix/build/emacs/emacs/lib-src/fakemail.c -l:libdld.sl -o
fakemail

make: *** [fakemail] Error 1
Of course I'm happy with the gcc-build :-)
Thanks for the help,
Christoph
