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.

+! Test the fix for PR34438, in which default initializers
+! forced the derived type to be static; ie. initialized once
+! during the lifetime of the programme.  Instead, they should
+! be initialized each time they come into scope.
+!
+! Contributed by Sven Buijssen <sven.buijssen@math.uni-dortmund.de>
+! Third test is from  Dominique Dhumieres <dominiq@lps.ens.fr>
