Hi,
I build with gcc 4.0.1, and it pops a few warnings, mostly about sign
errors.
Besides these, I got one in the U3 code that I wasn't able to kill. I'll
follow up about that in a separate email but it doesn't hurt me as much
since I don't have U3 on my machine. :)
---
Remove various warnings that pops with gcc 4. All are PPC-specific
besides the last one.
