gcc 3.3 and coreutils

[Stefan Reinauer]

Hi LinuxBIOS hackers,

while working on a port to the freshly released AMD64 Opteron systems
I fixed a couple of warnings that probably occur due to stricter gcc 3.x
syntax checks. This includes type signedness checking and stricter
string concatenation.
Also I noticed that coreutils 5.0 are stricter with their POSIX
compliance in a way that breaks LinuxBIOS scripts. tail -5 has to be
tail -n 5, head accordingly.

I have not explicitly tested older compilers, but the changes are
harmless and unlikely to break anything. Can this be included?

Comments?
