Alexandre, are you deadly sure that the current mainline emits the warning?
The whole thread started with Andrey observation that gcc does *not* 
warn. At the time I supported him, having verified that indeed it 
does'nt with -Wall and/or -Wuninitialized. Unfortunately I don't have 
here my snapshots to check again.

Ciao, Paolo.
