Documentation/Changes (maybe) reflects the minimums across all 
architectures, which really has never applied to any single architecture 
for a long time.  x86 requires gcc 3.4 at a minimum, for example, and it 
is not clear that that is sufficient anymore, either.

We don't really have good documentation about what the requirements for 
various specific arches are...

That being said, it sounds like this one is justified.
