I think that there are two problems:

1) Your scheme requires that all possible implementations can be parsed by
the compiler - that won't be true for macros describing defects.
2) Your scheme can't cope with optional features (long long or
<someheader.h>).

Oh, and macros are probably simpler, if ugly.
