obtained gcc-4.6.4.tar.bz2 from upstream website;upstream

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.

+// * has no non-standard-layout base classes,
+// * either has no non-static data members in the most-derived class and at
+// most one base class with non-static data members, or has no base classes
+// with non-static data members, and
+// * has no base classes of the same type as the first non-static data member.
