It is implementation-defined whether or not the contents of a #pragma directive
are macro expanded--I think that VC allows it.  C99 explicitly allows it, but
says that any #pragma that begins with STDC is explicitly _not_ macro expanded.
C99, of course, has the _Pragma operator which can be generated by a macro
expansion (not that that is relevent here).
