Compile errors on SuSE 9.3/AMD64

Not that I didn't get it to compile correctly, but there are a few 
things that just don't work right on SuSE/AMD64 - probably due to the 
AMD64 libs being a bit different than the 32-bit ones.

1. What works.

./configure --disable-gnomemm

Without gnomemm-support workrave compiles without a hitch once the 
necessary devel-rpms have been installed.

2. The first option which doesn't compile.

./configure

Configures nicely, compile fails with these errors:
