If you want to preinclude a header for all compilations, see my patch
<http://gcc.gnu.org/ml/gcc-patches/2009-04/msg01444.html>. You need to be
very careful when doing so about what goes in such a header, because it's
valid for source files to define feature test macros before including
system headers, but such feature test macros will be defined after such
preinclusion, so the preincluded header mustn't depend on feature test
macros.
