Thanks for the feedback.

I checked the following boxes which I have access to:

FreeBSD-CURRENT
Red Hat Linux 7.3
MacOS X 10.2.2
Solaris 2.7

All of them had <stdint.h> except for Solaris.
All of them (including Solaris) had <inttypes.h>

One FreeSBD, MacOS x, and Linux, <inttypes.h> includes <stdint.h>

So I think this new patch is good.

I also introduce a macro HAVE_INTTYPES_H, so if
an autoconf style test is written to detect the presence of this header,
then it can be used.
