Actually, it was on the Netwinder site that I found the erratum about GCC
being broken for certain optimizations. They claim it's purely a GCC on ARM
What versions of GCC are being used between the two Netwinders, I wonder?
The build farm on handhelds.org is some sort of odd crossbreed between Redhat
and Debian..I don't believe it's running on Netwinders, but some sort of
internal Compaq development platform.

Hmm...well, I think gdb used to be on my iPaq but I had to blow it away to
make space for Squeak. I might be able to get it back on, however...debugging
should be quite easy since there is a shell login hanging off the iPaq serial
I'll see what I can do..right now I'm trying to get OSProcess working with my
shrunken image so I can completely do away with the window manager on the
iPaq...that way I can call /sbin/shutdown and whatever else (the irda stuff?)
right from Squeak. It would be nice be able to do away with X as well, but
one step at a time... ;)
