	I hate to bother all of you apparent C gods out there with a question
about something as trivial as FORTRAN, but the faculty here insist on using
it.
	Question:  In Think C, you can choose, via which library you link, 
whether your code will utilize SANE, the FPU, or a little bit of both.  What
I am wondering, since my prof asked me, is in Absoft FORTRAN/20 when you choose
to use the 68881/68882 optiion, is SANE totally bypassed and the built in 
coprocessor functions are used exclussively or does it still use SANE in order
to get the 96bit (I think it's 96 but I've been wrong before (yes, it's true))
precision.  Also the same question applies to Language Systems FORTRAN.  Do
any FORTRAN compilers give you this control.
	Also, as long as you're here, does anyone know if SPAM can totally
bypass SANE, and itself, it send all calcs to the FPU.  I only recall it being
for use in systems w/o the math chip.
	Finally, what about the Radius SANE patch, is there somewhere I can get
a copy to play with w/o buying the whole damn board. (Perhaps someone could 
e-mail me a copy?)
