I'll just build 4.8 and 5.0 versions then and see how that gets by.

setiathome-3.08.i386-unknown-freebsd4.8: ELF 32-bit LSB executable,
Intel 80386, version 1 (FreeBSD), for FreeBSD 4.8, statically linked,
I agree, this application is more for platform advocacy than it is
anything else these days. I use it to burn in machines because it helps
peg the proc and memory.
Yesterday I built it statically with optimized libc and libm. For libc
I used `-O3 -pipe', because it wouldn't compile with the flags I used
for libm and setiathome: `-O3 -fno-exceptions -fno-rtti -funroll-loops
-fomit-frame-pointer -fno-strict-aliasing -fno-common -pipe'. Since I
normally use `-O -pipe', I'm hoping there are people here who can give
me optimization suggestions. Would making it i686 only help?
So, I got a report back from a guy who tested it. He normally runs the
linux binary and said that it's still about a half hour faster. If
you've run setiathome much then you know a half hour difference is good
because the work units vary. I gave him a reference unit used to test
the clients. Anyway, one would have to use the reference unit on both
to get a fair time trial.
Anyone interested in testing please e-mail me.
