Summary: Is twice as much double the fun?

Does anyone happen to know whether the Ultrix C compiler has a way to
control whether "double" means "D" or "G" double precision floating
point?  (I would RTFM if I had one.)

[ Yes, you can do this.  On the cc command line, specify -Md
for D format numbers (the default) or -Mg for G format
numbers.  If you use G format numbers and functions from the
math library then you must also load with -lmg instead of
-lm.
