I dimly recall some, but this should no longer be a problem now that
autoconf tests the include files serially.  That is, it no longer
defines HAVE_STDINT_H if <inttypes.h> works and the combination of
<inttypes.h> followed by <stdint.h> does not work.

Fixing this requires fixing Autoconf, gnulib, coreutils, and probably
other platforms.  I've started the ball rolling by installing the
following into Autoconf.

2004-01-26  Paul Eggert  <address@hidden>

        * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
        HAVE_INTTYPES_H is defined.  This is needed on Tru64 5.1b with
        Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
        not <inttypes.h>.  Problem reported by Tim Mooney in
        <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
        * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
        Likewise.
