Ok, you mean c99 support. :-)

2.95 is really ancient.

You mean declaring a variable ("z") somewhere else than at the start of
the code block?  I don't like that either...

Gcc 2.95 had quite limited support for C99, see:
	http://gcc.gnu.org/c99status.html

C99 is quite different from C.  While e.g. C++ is compatible with
c89, it's not really compatible with c99 (don't now remember
the details though).
