Merging Apple's Objective-C 2.0 compiler changes

[Nicola Pero]

Can we (legally) merge Apple's Objective-C / Objective-C++  
modifications to GCC into FSF GCC trunk ?
Any legal obstacles ?

If we start producing patches to the current FSF GCC trunk that merge  
these modifications, would they be accepted ?

I think Apple would benefit from merging of their modifications in  
that we'd merge the Apple/NeXT runtime support as well. :-)
They don't have to do any work.

Thanks
