Proposed wwwdocs patch to explain the apparent performance regression
Here is a proposed patch to gcc-4.5/changes.html, which mentions the apparent
performance regression (and describes how to avoid it) in the "Caveats"
section.
The FSF should have my copyright assignment; in any case I think this patch is
trivial enough.
