Hi Kevin,

Default on PowerPC is GCC 4.2.1

Its hard to see that this wouldn't turn up elsewhere on other arch' stop though as from what I seen doesn't seem to be dependent on PowerPC alone.

But to confirm my previous build, after backing out udplite the build did complete just fine. I'll find out in a little while whether it runs :-) crossing fingers.
