I have a seismic forward modeling program running fine on an i386
machine, but has a big problem with NaN's on my mac 7500.  I think i
have an alignment problem, but can't tell.  I would like to detect
floating point exceptions.  I tried looked for the fpu_control.h include
file described in "info g77", but can not find it.  Is there a provision
for floating point exception handling for g77 on macppc?  If so, where
do I find it?

More generally, g77 crashed on my during compiling with optimization set
to "O".  Are there big problems with g77 for macppc netbsd 1.5?

Thanks in advance.
