[Mesa-dev] [PATCH 1/2] mesa: bump required GCC version to 4.4.0

[Timothy Arceri]

From: Timothy Arceri <t_arceri at yahoo.com.au>

The last time this was bumped we settled on 4.2.0 because OpenBSD
wasn't willing to ship anything greater than 4.2.1 (as that was the
last GPLv2 licensed version) however they now ship 4.9.3.

As far as I can tell the oldest distro still using a current version
of Mesa is Red Hat Enterprise Linux 6 which ships with 4.4.7.

The following patch will make Mesa require at least GCC 4.3.0 to build
however setting an artificial at 4.4.0 means less wasted developer
time deciding what features of GCC can be safely used in future.
