FWIW: we tried doing that in the Mercury project, but autoconfing it
properly was more difficult than we first thought, and eventually after
several failed attempts we gave up and just used our own type names
`MR_uintptr_t', `MR_intptr_t', etc., to avoid various conflicts with
system header files.

For example, one such conflict was that we were checking for these types in
<stdint.h>, and Solaris 2.X.Y did not have <stdint.h>, so we were declaring the
types ourselves, but Solaris 2.X.Y did have <inttypes.h> and #includes that file
from <sys/types.h>, which conflicted with our definitions of intptr_t etc.
