That's the thing, it's not available.  Or at least, it's not
where the other
standard headers are located.  And from the log and such, I
can't figure out why
configure thinks that it is available.

Yes, I've looked at "configure --help", but
nothing there seems to be related to this issue.  And yes,
configure.ac is included with the bison package, but there
is no reference to stdint.h.  Here's all that's there:

# Checks for header files.
AC_CHECK_HEADERS_ONCE([locale.h])

I'll check the Autoconf manual and also see if there's an
autoconf mailing
list to which I can send email (if I don't find the
information I need in the
manual).
