Hello!
My attempt to compile 2.5.46 with gcc 3.3 resulted in over 66% lines of the
form:
xyz.c: warning: comparison between signed and unsigned
This is a first step to eliminate those, covering arch/alpha. Most fixes
are obvious, but please check.
BTW who is the current maintainer for Alpha issues? MAINTAINERS has no
entry :-/
Thorsten
