GNU Astronomy Utilities (Gnuastro) uses GNU Autotools. A Gnuastro developer
encountered the "Numeric user ID too large" error when generating a tarball
with the 'make dist' command on his macOS (Monterey 12.3) laptop. His user id
is an integer with 9 digits, which is too big for the old v7 and ustar formats
of tar.

The issue is discussed in Savannah bug #65578 (of Gnuastro), where the
work-around conclusion was to use a conditional that adds 'tar-pax' to
'AM_INIT_AUTOMAKE' when the user ID is so large. For reference, here is
Gnuastro's configure.ac:
https://git.savannah.gnu.org/cgit/gnuastro.git/tree/configure.ac#n44

Even though we encountered this problem in macOS, this problem may not be
limited to it. Other user management systems who use such large IDs may also
cause this issue.

While it is possible to write such workaround downstream in Gnuastro, it would
be nice to have the issue solved upstream in the GNU Autotools since it can
happen for any other developer of other software that uses Autotools.
