I'll post the info as a reply to the first mail in this series. I have
fairly recent gcc (4.1.1) and I don't see us dropping support for it in

What's important is not support lifetime, but whether or not the warning
persists through version 4.1.2, 4.1.3, etc.
We don't want to add markers for compiler quirks that come and go.
The current markers tend to exist for a class of problems that gcc
fundamentally has a tough time "seeing." Different optimizer behaviors
from compiler version to compiler version are just noise[1].
