Fixing some warnings compiling renaissance

[Sebastian Reitenbach]

Hi,

attached patch fixes some of the the warnings seen when compiling 
Renaissance SVN against gnustep-base from SVN. Those warnings 
can be seen in attached WARNINGS file.
Using clang 3.2 on OpenBSD 5.3 i386. There are still warnings left,
which can be seen in UNFIXED-WARNINGS, but I don't know how to get rid of it 
easily.
Maybe someone else has the mood to look at it, or can give me an idea ;)

Is the patch OK?

cheers,
Sebastian
