The pendency of a standardized-in-C23 "static_assert" and groff's own
provision of an "assert.h" file is causing problems on macOS.

See https://lists.gnu.org/archive/html/groff/2023-02/msg00028.html  for
details.

The right solution may be to simply drop groff's assert.h; our "INSTALL.extra"
file already says we require C99, and gnulib itself no longer seems to support
C89 <https://lists.gnu.org/archive/html/groff/2023-02/msg00034.html>, which
means we no longer support it either.
