I'm not an expert on systemology, so I cannot judge this.  Hopefully other
people will answer you (Paul?).

(On my system, GNU/Linux with GNU libc, sys/bitypes.h is only includes
sys/types. so the change wouldn't make difference.)

I think you can get the "add" this way:

AC_CHECK_TYPE(u_int8_t, , , [AC_INCLUDES_DEFAULT
#if HAVE_SYS_BITYPES_H
#include <sys/bitypes.h>
#endif
])

Just a quick hint, I haven't time to test this, sorry.
Please tell us whether this worked.

Good luck,
