A:
You can find the list of C++-0x features supported and the G++ version that supports them here. There is a simple Yes in the column so I assume they're in 4.3 or possibly earlier.

The linked page shows the compiler version now if the feature is supported.

But not in the case of "extern templates". It's simply a Yes there. However, IIRC it was people from GCC that proposed the idea, so it's possible that it has been in g++ for several versions.
