Thanks for noticing. This warnings only seem to be issued by older
versions of gcc, which is probably why two compilers give the warnings
while one doesn't.
The variables can never be uninitialized, because they are guarded by
ifs and older versions don't seem to recognize that. I'll fix them
in a re-roll though (or a separate patch if that's preferred), just
waiting for some feedback for v4 of my series.
