warnings in 3.3: comparison of unsigned expression < 0 is always false

[Christian Joensson]

In http://gcc.gnu.org/ml/gcc-testresults/2003-05/msg00405.html, I get
the follwingcompilation warnings:

stage2/xgcc -Bstage2/ -B/usr/local/gcc-binutils/i686-pc-linux-gnu/bin/   -g -O2

Is there something we could do about them?
