From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001
From: upstream source tree <ports@midipix.org>
Date: Sun, 15 Mar 2015 20:14:05 -0400
Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified
 gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream
 tarball.

downloading a git-generated archive based on the 'upstream' tag
should provide you with a source tree that is binary identical
to the one extracted from the above tarball.

if you have obtained the source via the command 'git clone',
however, do note that line-endings of files in your working
directory might differ from line-endings of the respective
files in the upstream repository.

+Tests in this directory are for functionality that has changed in GCC
+from one release to another or that is not ABI-compliant and may change
+in a future release.
+
+Each test header for changed behavior should indicate the version in
+which the behavior changed, in order to help users of these tests to
+determine whether a test failure is expected or not.
+
+Every test in this directory that covers behavior that is not
+ABI-compliant should also be covered by a test for -Wabi to ensure that
+there is a warning for the construct.
