It'd be nice if someone added support for
use-64-bit-pointers-if-available to Autoconf, much as AC_SYS_LARGEFILE
added support for 64-bit off_t on platforms that supported that.
Nobody has done it yet, as far as I know.  You can look at
AC_SYS_LARGEFILE for some ideas about how to do it.

Right on both counts.
