# NOTE: Nonstandard flags here.
# On 14.0, we used -O2 and everything was fine. On 14.1, using -O2
# causes a segfault on 'open mailbox' or 'examine mailbox'... but
# it doesn't happen with any of -O0 -O1 -O3. I'm not a Fortran guru,
# so I can't say whether the bug is in dungeon or gfortran. So to
# be on the safe side, this script uses -O0 to completely disable
# the optimizer.
