[Spice-devel] [PATCH 0/9] fix a bunch of set but unused warnings

[Alon Levy]

This is the downfall of me running rawhide and having been upgraded
to gcc 4.6.0 recently.

But it's all good, since it's really things we want to fix. Some of the
comments are a little more verbose then required, (talking about the third
patch, remove unused error val).

The only tricky bit is in the demarshaller/marshaller, since the downside of
having code generated is that you sometimes need to fix the generator.. I tried
doing a really swanky track-used-variables before I did this simple fix, and
discovered some hidden dragons (the subwriter's are not correctly scoped), but
I think my final solution is good - higher level and more specific.

Also the first patch could be split if someone insists.

I'm suggesting these for 0.8 too since they are basically bug fixes.
