Simon,

Very much appreciated - thank you.

For the archives: from the linked reference the details for a CeleronD
processor, with /proc/cpuinfo model name of "Intel(R) Celeron(R) CPU
XXXGHz" are:

CHOST="i686-pc-linux-gnu"
CFLAGS="-march=prescott -O2 -pipe -fomit-frame-pointer"
CXXFLAGS="${CFLAGS}"


I'll see what further pain I can inflict on my slave with these
settings and report back.

Thanks,
Nick
