Thanks Paul, I'll try to fix it tomorrow. Is there a compiler defined
preprocessor symbol that I can add which covers OSX. For example:

#if !defined(__FreeBSD__) && !defined(__NetBSD__) && \
    !defined(__OpenBSD__) && !defined(__linux__)
# define NEED_INT_N
#endif

Is there __OSX__ or similar? If there is, simply add

	&& !defined(__OSX__)

to that second line, which is around line 71 in tools/apout/defines.h.

Thanks,
