I forgot to mention that, once you tested for the above two headers,
you test for the specific integer types with the two headers included

    AC_TYPE_UINT8

etc.

While Autoconf may not be a panacea (I don't claim it ever is),
it does solve 99% of the problem.
Testing for the platform has the feature of not distinguishing which
version or instantiation of the platform works.  That is no good when
all that is needed is a functionality.

For example, if you test the above on solaris 8 but running GCC-4.5 (upcoming)
you are likely to get the headers and everything works perfectly.
