Annoyingly enough my patch isn't good enough, it turns out that ctypes
has introduced a SIZEOF__BOOL definition in configure.in and that needs
special caseing as well.
pymacconfig.h.patch2 fixes that issue as well. Do you have access to a
PPC G5 system? I've determined the correct value of SIZEOF__BOOL for
that platform by reading the assembly code for a small test program and
hence am not 100% sure that sizeof(_Bool) actually is 1 on that
architecture.
One other annoying issue cropped up: regrtest.py consistently hangs in
test_signal (with 100% CPU usage) when I run it in rossetta (PPC
emulator). I'll test this on an actual PPC machine as well, this might
well be an issue with the PPC emulator.
