Some projects have been ported to Apple ppc64. In that case, they may test macros like this:
#if defined(__ppc64__) #endif
GCC does not define __ppc64__ (lowercase). It defines __PPC64__ (uppercase). To make the above code also build on Debian ppc64le or ppc64 (big endian) change the above code to:
#if defined(__ppc64__) || defined(__PPC64__) #endif
Details discussed on #talos-workstation:
Apple's gcc (4.0.1) in MacOS 10.5, ppc32 headers define:
__POWERPC__ and __ppc__
with -m64, the following are defined:
__POWERPC__, __ppc__, and __ppc64__
GCC compiling for the Linux kernel defines, for ppc32:
__PPC__ and __powerpc__
and for ppc64:
__PPC__, __powerpc__, __PPC64__ and __powerpc64__
