Visual C++ 6.0 (SP3) is the best one. Egcs 1.1.2 is very close and even better in some C++ related stuff. I would recommend to use egcs instead of Visual C++ if you target scientific applications. Codewarrior 5 is a little bit slower (15%) but performs quite well with floating points (2% slower). Please have a look at the marvelous bench++ suite at http://www.research.att.com/~orost/bench_plus_plus.html Regards, William William Gacquer Ubi Studios - Ubi Soft Entertainment > -----Original Message----- > From: Reza Habib [SMTP:reza AT psych DOT utoronto DOT ca] > Sent: Monday, July 12, 1999 7:23 PM > To: Cygwin Mailing List > Subject: optimization > > Hi.
