I guess, we both right here - git HEAD uses AC_CHECK_TYPES(), which,
amoung other things, defines corresponding HAVE_* macro, but all the
realeases up to latest 3.4.0pre2 use older macro - AC_CHECK_TYPE(),
which doesn't do that.. So, future releases may have these macros
defined, but not sure, in which branches? 3.0, 3.2, 3.4?

Also, it maybe worth mentioning, that there are a bit more complex and
extensive checks for this particular types, than AC_CHECK_TYPES:

AC_TYPE_INTPTR_T
AC_TYPE_UINTPTR_T
AM_TYPE_PTRDIFF_T

They not just check validity of the types, but also define them, if they 
are missing. That's true at least for autoconf 2.62.

With best regards,
Timur Bakeyev.
