I know, but...

...if it was "add", it would be perfect. It is, however, "replace", ie.
either default includes, or whatever is there. I am not even sure, how
am I supposed to put default includes there (I'd rather not reinvent
includes which should be there to check everything).

I still think that autoconf (at least when doing AC_CHECK_TYPE) should use 
#if HAVE_SYS_BITYPES_H
#include <sys/bitypes.h>
#endif
because some types can be defined there.
