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.

+// PR c++/10091
+
+// Original synopsis
+// Bug: We were dying because in general, B::a doesn't have enough
+// alignment for us to take its address.  But if the B is C::b, it does
+// have enough alignment, and we should be able to determine that.
+
+// This only failed on STRICT_ALIGNMENT targets (i.e. not i686)
+
+// July 2003
+// packing of non-pods is now only allowed if the non-pod is itself
+// packed. Also only such pods can be reference bound to non-consts
