The OS is WinXP. The CPU with the big timing difference is Pentium M
1.1GHz 
(a laptop).

But when I tried it on a Pentium 4 2.93Ghz machine, the differences were 
minimal; although the new CALL EBX form seemed to be 5% faster than the
old 
CALL (EBX) form. And on this machine, on my second test, lccwin was anyway

faster than gcc!

So I wouldn't worry about it too much; I will discover other things I'm
sure 
pretty soon. That code on the Pentium M must have been a strange
combination 
of different factors.

Maybe best to keep the new code though, if only because that's what gcc 
seems to use.
