mutter 3.6.0 compile failes using gcc 4.7

[Maik Greubel]

Compilation of mutter 3.6.0 failed using gcc 4.7.1 with this error:

core/prefs.c: In function 'meta_prefs_set_num_workspaces': core/prefs.c:1672:23: error: 'pref' may be used uninitialized in this function [-Werror=maybe-uninitialized] core/prefs.c: In function 'meta_prefs_set_no_tab_popup': core/prefs.c:2151:27: error: 'pref' may be used uninitialized in this function [-Werror=maybe-uninitialized] cc1: all warnings being treated as errors

Fixed by attached patch.

I've built Mutter with GCC 4.7.1 and I didn't notice any problems. I have 4.7.2 currently. I'll check it again.

As you see in attached build.log, it works great with 4.7.2 and it worked very well with 4.7.1 here. Unless someone else confirms this, I'll mark it as "worksforme".

Same for me, I had no problems to compile it (I'm still with gcc 4.7.1). It has a huge number of deps when we ask for it:

As the author didn't reply for some time and the package appears to work for at least two of us, closing this ticket.
