I did have GDC hooked up to the C pre-processor macros, which defined
a lot of target-specific identifiers (GNU_SSE, GNU_SSE2, etc)
depending on the default target flags, and what extra target flags you
passed to the compiler - but was dropped because of growing number of
stub dependencies it incurred, and the fact that most macros were
about as useful as marmite sundae.   I would be certainly up for
addressing this in a pragmatic way though.
