Warnings while building cross-compiler


Hello

I'm trying to build a GCC 3.0.4 based x86 -> PPC cross compiler using
gcc 2.95.3. While compiling, there are a lot of warnings of the form
"comparison between signed and unsigned", for example in gcc/alias.c,
gcc/combine.c and gcc/reload.c.

Is this something to worry about (environment and/or tools broken) or is
this normal "behaviour", which can be ignored?

TIA

Dave
