	There are bogus warnings, and there are warnings which gcc is
*documented* as not being able to detect are unnecessary.  E.g., from
the gcc manual for -Wuninitialized:

	I believe the warnings I fixed above are of this variety, only
a lot more complicated.  I don't believe that when gcc's flow analysis
is fixed it will affect these types, so may I install this patch?

	Also what about all the other entries in that patch, are they
okay?
