	Because MARK(!) brought them into the discussion.  This is really
getting annoying.

	While xlC uses different name mangling, Mark's statement about
template instantiation is false.  xlC has various template instantiation
options.  The default behaves similar to G++'s current behavior.  G++
currently does not implement the more complicated solutions which would
allow all of the correct semantics on AIX.

	Arguing that because G++ is not compatible with xlC in some
(important) ways, does not give G++ license to gratuitously add more
incompatibilities in behavior.  There *IS* some compatibility between G++
and xlC.  Just because one cannot link the object files together does not
mean that the rest of the argument can be ignored.
