This may be the problem.

Autoconf works by calling little programs and setting shell variables to
appropriate values based on the results, which are then used for various
purposes.  What I called "functions" are really m4 macros (for the m4
macro processor);  input files for Autoconf (`configure.ac') consist of m4
macros which often contain arguments consisting of strings which are
passed to the shell, which should be the Bourne shell.

You can look up the m4 macros to see what they do, but I don't think this
should be necessary.

There are some common tests which are performed, so some other macro may
be testing for `stdint.h'.  If Bison requires `stdint.h', I wouldn't
expect it to work if it's missing.  I'm not familiar with this header;  it
sounds like it would contain fundamental declarations, but perhaps they
are in some other header file on some systems.  If it's in an unusual
place, this might be something the Bison maintainers should know about.

I wouldn't expect there to be an option for this.

A quick-and-dirty solution might just be to copy `stdint.h' into the
directory with your other headers, or into the directory in which you're
installing Bison.

There are several lists:

You're welcome.
