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 the fix for PR27269 and PR27xxx.
+! The former caused a segfault in trying to process
+! module b, with an unused equivalence in a. The latter
+! produced an assembler error due to multiple declarations
+! for a module equivalence, when one of the variables was
+! initialized, as M in module a.
+!
