[Spice-devel] [PATCH] Fix min gcc version for __attribute__(format)

[Christophe Fergeau]

We currently use it only on gcc 4.5 or newer, but it was actually
introduced much earlier than that. It's documented in gcc 2.95.3
manual:
http://gcc.gnu.org/onlinedocs/gcc-2.95.3/gcc_4.html#SEC84
and glib uses starting from gcc 2.2.5.
This commit uses the same minimum version as glib.
