[Gc] optional namespace for gc_cpp

[Alexander Herz]

Hi,

I ran into some name clash problems with beohm c++ (somewhere a value 
caled gc was defined).

As a fix I suggest to add GC_NAMESPACE define and the namespace boehmgc 
as outlined in the gc_cpp.h attached.
It's really a minor change (doesn't affect anything else but this header 
and it's optional). Would be nice to see it (or something similar) in 
the official version.

Regards,
Alex
