Good point. I've removed it and will post an updated patch.

However while investigating this I discovered this comment in 
winapi_check:

    # This checks for a bunch of standard headers
    # There's stdlib.h, string.h and sys/types.h too but we don't
    # want to force ifdefs for those at this point.

Why don't we want to force ifdefs for these headers?

Either they are conditional and then having ifdefs in only 1/10 of the 
time is useless.

Or they are not and then there's no point in having HAVE_SYS_TYPES_H & 
co.

Any objection to patches that would switch to strict ifdef enforcement 
for these headers?
