A small libio patch

A small libio patch

[H.J. Lu]

Here is a small patch for libio. After egcs is installed, I cannot
use gcc 2.7.2.3 anymore since _G_config.h is not compatible with
older gcc. This patch should fix it.

	* gen-params (__extension__): Use only if gcc version >= 2.8.
	(NULL): Add support for gcc version < 2.8.
