There is another problem with -fast on x86 that is probably the cause of
your problem. It implies -nofstore, and we needed to force storage on
some Fortran routines under g77/gfortran to avoid an infinite loop.
However, even if you set SAFE_FFLAGS, the likely problems with IEC60559
compliance remain.
