[C++] Extensions deprecated in 3.4

[Giovanni Bajo]

Hello,

http://gcc.gnu.org/gcc-3.4/changes.html lists the following two extensions as
deprecated:

Default arguments in function types have been deprecated and will be removed.
ARM-style name-injection of friend declarations has been deprecated and will be
removed. For example: struct S { friend void f(); }; void g() { f(); } will not
be accepted by future versions of G++; instead a declaration of "f" will need
to be present outside of the scope of "S".

I believe the latter is being taken care of by Kriang with his work on friend
name injection, right?

What about the first? Was it already removed from 4.0?
