Hi!

The recent messages about DJGPP's floating point library have somewhat
disturbed me. Therefore I have compiled paranoia (from netlib), to see whether
this program reveals some problems. Well, I have compiled it without
optimization (the program completely choked when I tried -O2, why?) and
paranoia said the following:

No chopping nor rounding on * / + - sqrt: sticky bit incorrectly used or not
used at all. 

Does anybody know why this is so?
(In case it has something to do with the math coprocessor: I have run it
on a 386SX + 387.)

Best regards,

Erik

BTW, a Pentium 120 Mhz here has just outperformed my Silicon Graphics R4000
workstation in a 20h long run of a Fortran program that was converted with f2c
and compiled with DJGPP v2! Isn't that marvellous?
