<pre>This is trivial to reproduce:
#include <stdbool.h>
#include <altivec.h>
And compile with clang (not clang++). The result is lots of "error: unknown
type name 'vector'".
AFAICT the problem is that stdbool.h defines bool to _Bool, then gets confused
when using types like "vector bool char" (which is "vector _Bool char" after
preprocessing).
I'm not really sure why, but it works in GCC. Maybe they just treat _Bool the
same as bool for AltiVec. It would be really nice if clang worked, too.</pre>
