That's not the way GCC (or egcs) has been operating.  If someone wants
to propose a contribution she is welcome; there is/was no explicit go-
ahead from whoever GNU may refer to, though.  Most of the new C++ ABI
has been implemented by CodeSourcery.

There never was an official GCC release 2.91.  GCC 2.95 was the first 
after the egcs/gcc -> GCC merge.  GCC 3.0 was next.

GCC 3.3 and 3.4 have C++ ABI changes, not sure what you are referring to 
here?

Because it _was_ egcs. :-)

SUSE has been supporting XFS for more than half a dozen years.
