Hi Peter,

long time no read :)

Thanks for the patch, I've checked it in. You may want to give 
--enable-pxa a try to adapt SP_OFFSET to Xscale. :) I've also ripped out 
some things in the CVS in config/arm and replaced them with code from 
GNU libc (COMPARE_AND_EXCHANGE, mostly). I hope these work better for 
you, too.

Is there going to be an arm-RISCOS port of 1.1.4? I've read the news on 
the gcc 3.3.3 port on drobe, and hoped that someone would pick 1.1.4 (or 
even 1.1.4+arm-CVS-changes) up and give it another go on RISC OS.

cheers,
