I've done this with 2.1.0. It will work perfectly fine. However, it definitely will not work with any of the *really* spiffy optimization flags. If memory (it's been a while) serves, the compile dies if you use -mpentium -O3 (or greater). There's alll sorts of comparison between unsigned to signed integers warnings. As for speed, I never did bother to benchmark things. : Many thanks, : Gary : -- : pub 1024/C001D00D 1996/01/22 Gary Howland <gary@systemics.com> : Key fingerprint = 0C FB 60 61 4D 3B 24 7D 1C 89 1D BE 1F EE 09 06 -- Giao Nguyen Computer Science Student Will program for food
