There is one serious bug.  Floating-point numbers don't work!
The output is always %.12g
I've stepped through the code (with cpr) in the function:
	Objects/floatobject.c: float_buf_repr
and I can't see it.  I switched from sprintf to gcvt and it makes no
difference.  I've used SAS/C 6.55 and 6.51, tried various combinations
of floating-point representations and optimisations and it always gives
%.12g.  I've also compiled the same code for OSF/1 (native cc) and
HPUX (gcc) without problems, so it must be a bug in SAS/C.  Because
the test program works without problem, I suspect it might be a
(s)link problem.

Perhaps someone would like to try gcc or DICE, or you have any other
suggestions, please send e-mail.
