I wish this were the case, but alas I continue to see fairly trivial false
positives from -Wuninitialized.  Usually cases where the initialization
and the use are both protected by equivalent conditionals at different
places in the function.

Personally, as a matter of *style*, I eliminate such cases either by
initializing the variable or restructuring the function.  But this is very
much a question of style, not of correctness.
