Hi!While generalizing some code from FFTW to check for compiler flags from C to Fortran, I ran into an issue with autoconf. It seems that ac_test_FCFLAGS and ac_save_FCFLAGS are never set because in fortran.m4 it is hardcoded as:
ac_test_FFLAGS=${[]_AC_LANG_PREFIX[]FLAGS+set}
and
ac_save_FFLAGS=$[]_AC_LANG_PREFIX[]FLAGS
Changing these to
ac_test_[]_AC_LANG_PREFIX[]FLAGS=${[]_AC_LANG_PREFIX[]FLAGS+set}
and
ac_save_[]_AC_LANG_PREFIX[]FLAGS=$[]_AC_LANG_PREFIX[]FLAGS
fixes this behavior. There are 2 of the former, 4 of the latter. A
patch is attached, as is testsuite.log. With a bit more time, I can
probably provide a test as suggested in README-hacking, too.
