I decided to give -fprofile-generate/-fprofile-use a try. Now, at revno: 104508, all files compile, except that "Dumping under the name emacs" fails:

        --- Load Commands written to Output File ---
Writing segment __PAGEZERO @ 0 ( 0/ 0x1000 @ 0) Writing segment __TEXT @ 0 (0x403000/0x403000 @ 0x1000) Writing segment __DATA @ 0x403000 (0x27e000/0x27e000 @ 0x404000)

                section __la_symbol_ptr  at 0x59dd08 - 0x59e7a8 (sz:    0xaa0)
        unexec: unrecognized section name in __DATA segment
        make[1]: *** [bootstrap-emacs] Error 1
        make: *** [src] Error 2

After a 'make clean' I just invoked a simple make. Is this due to the - fprofile-generate option to GCC 4.5.2 on Mac OS X 10.5.8 PPC? (Libgcov gets used.) (More compiler output available.)

After re-configuration without -fprofile-generate in CFLAGS temacs and bootstrap-emacs compiled OK and were built ...
