Subject: [PATCH 3.8 17/81] compiler-gcc4.h: Reorder macros based upon gcc ver

3.8.13.12 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Daniel Santos <daniel.santos@...ox.com>

commit 6640dfdf6fff387c0a8f7fb8ac1d47c6b093484e upstream.

This helps to keep the file from getting confusing, removes one
duplicate version check and should encourage future editors to put new
macros where they belong.
