thanks Charlie, that's just what I was looking for.
Is that without using the Maverick or is that where the boost comes from?
I've had to limit what I was doing uptil now because it was struggling a bit
with the data load.
I've spent a lot of time working on migrating to eabi and I was starting wonder
if it was worth the effort. It looks like it most definately is.
I just need to stop the cross-compiler trying to use the host's libc in portmap
and I may be getting close.
