| Removing the ending `dnl' here solves the problem.

Thanks.  The proper fix is

m4_ifdef([_AC_LANG_PROGRAM_C_F77_HOOKS], [_AC_LANG_PROGRAM_C_F77_HOOKS()])dnl

It's not clear to me whether `Removing the ending `dnl' here solves
the problem' means AC_F77_WRAPPERS works properly.  Please, confirm so
that I can resume the release process.
