Funny you should mention that. I just compiled gcc-3.3.4, recompiled
msp430-libc (had to remove a few part types that are not supported in
the CVS patch), and I am able to compile the TinyOS application. With a
load of warnings, though. The application still doesn't work on the
target, but it is possible that this is a problem on my end.
I forgot to mention in my original post that I was using gcc-3.2.3.
The warnings are attached below, in case anybody has a suggestion as to
what they mean (I don't know what 'strict-aliasing' means).
