Never underestimate entropy. Though Sun has pretty much standardized on IEEE,
their "f77" manual page lists the following options, several of which require
you to know who made your floating-point chip: -cg87, -cg89, -fnonstd, -f3167,
-f68881, -f80387, -ffpa, -ffpaplus, -fsoft, -fswitch, -fstore. :-)
Don't forget the most handy of them all
-fast
Which among other things, selects the optimal mode for the machine
that you are compiling on.
Note that for most of the options, what is selected is performance
.... if you don't care how fast it goes you don't need to say anything.
