Failing to precompiling would a problem (and IMHO better).

But in any case, headers must be tested in autoconf with the same definitions 
as they will be included with. autoconf normally does that automatically. But 
if some definitions is overriden, then I don't see any clean alternative to 
Rafaël's hack.

Otherwise the reciprocal problem shows up:
the header succeeds in autoconf and fails in make!


So unless you're suggesting to drop Windows XP/2003 support (fine with me), I 
don't see any better solution.
