Yes, I suspect that Larry's recommendation may be better.

If <inttypes.h> exists, then it will include <stdint.h>
according to:

  http://www.opengroup.org/susv3xbd/inttypes.h.html

(the URL given in gnulib/lib/inttypes.h)

In the particular case of windows-NT, there is
neither an <inttypes.h> nor a <stdint.h> unless
either of them are generated by GNULIB macros, so
there is still a bit of a confusion in how the
config.h file should be generated along with the
Makefile.am files to specify one or the other or
both.
