Unfortunately, there's quite a dearth of information on this patch,
so I can't say.  I think it needs some testing before a decision can
be made.

What compilers have been tested with this?

As the help comments intimate that it needs at least gcc 4.4, and
you've changed it to produce a compile time warning if the option is
disabled, what's the implications for older compilers?
