Two thoughts: +1
And: Which headers are currently included?

I just tried this out in the shell..

igalic at unstable10x ...ar/pkg/hwloc/trunk/work/solaris9-i386 % for f in $( find install-isa-i386/opt/csw/include/ -type f ) ; do
x86="${f}"
amd64="${f/install-isa-i386/install-isa-amd64}"
diff -D __amd64 "${x86}" "${amd64}"
done

And found some rather disturbing things

/* Defined to 1 if you have the <stdint.h> header file. */
#ifndef __amd64
/* #  undef HWLOC_HAVE_STDINT_H */
#else /* __amd64 */
#  define HWLOC_HAVE_STDINT_H 1
#endif /* __amd64 */
