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.

+If the references in this example are changed to pointers (change
+all `&''s to `*'), no warnings result.
+
+I think this is incorrect according to CD2 5.2.11, para 4:
+
+4 An  lvalue of type T1 can be explicitly converted to an lvalue of type
+  T2 using the cast const_cast<T2&> (where T1 and T2 are  object  types)
+  if  a pointer to T1 can be explicitly converted to the type pointer to
+  T2 using a const_cast.  The result of a reference const_cast refers to
+  the original object.
