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

$file setiathome-3.08.i386-unknown-freebsd4.8
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.
