Subject: Pointer Signedness Errors When Compiling 1.8.4

Hi,

I'm working on compiling Ruby 1.8.4 on Ubunty Breezy (5.10) using gcc 
4.0.2 (20050808 prerelease Ubuntu 4.0.1-4ubuntu9). When make is run, 
compilation will complete and Ruby will run but I receive a lot of 
warnings about pointer targets differing in signedness. (Warning 
messages at bottom of message.)

Should these warnings concern me? Do they indicate that my Ruby build 
will have problems (like segmentation faults)? Is there any way I can 
fix the warnings?

Thank you,
Ben
