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.

+--  This unit provides public 'View' data types from/to which private vector
+--  representations can be converted via Altivec.Conversions. This allows
+--  convenient access to individual vector elements and provides a simple way
+--  to initialize vector objects.
+
+--  Accessing vector contents with direct memory overlays should be avoided
+--  because actual vector representations may vary across configurations, for
+--  instance to accommodate different target endianness.
+
+--  The natural representation of a vector is an array indexed by vector
+--  component number, which is materialized by the Varray type definitions
+--  below. The 16byte alignment constraint is unfortunately sometimes not
+--  properly honored for constant array aggregates, so the View types are
+--  actually records enclosing such arrays.
