Very probably nothing has been done. Volunteers are always welcome. 
Realise, though, that this would be patching GCC itself which would 
require paperwork filed with the FSF to get patches into the main tree. 
See the GCC website for more information.

At the very least, you can always fill out a "Enhancement Request" in 
the GCC bug tracker. Doing this would keep the issue from getting lost. 
Again see the GCC website for more details on filling out a bug tracker.
