I tried this on my own machine, and found out that -faltivec causes
Darwin's gcc to add about a dozen predefined macros (compare -dM output
with and without it). The gem that's killing us is
#define bool bool
but it tromps on user identifier space in some other ways too, including
#define'ing "pixel" and "vector".
I cannot imagine any sane use for a macro defined as above, so I'd
suggest filing a bug report with Apple.
We could kluge our way around this with something like#ifdef __APPLE_CC__#undef bool#endif
in c.h, but I'm a little worried what impact this might have on the
system header files. Why in the world have they got it doing that?
Meanwhile, this is a good tip to have in our archives.
