Since ereport() can now communicate to the compiler whether it returns
or not, a fair amount of "keep compiler quiet" code is dead. Since the
method that ereport() uses is not dependent on any compiler-specific
attributes, I think this code can just be removed. I propose the
attached patch.

Meh. This will only work if the compiler understands that abort()
doesn't return --- compilers that don't know that will start bleating
about uninitialized variables again. And the ones that do know it
will be able to throw away the dead code anyway.
I doubt this is a good idea.
