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 package defines the set of restriction identifiers for use by the
+--  compiler and binder. It is in a separate package from Restrict so that
+--  it can be used by the binder without dragging in unneeded compiler
+--  packages.
+
+--  Note: the actual definitions of the types are in package System.Rident,
+--  and this package is merely an instantiation of that package. The point
+--  of this level of generic indirection is to allow the compile time use
+--  to have the image tables available (this package is not compiled with
+--  Discard_Names), while at run-time we do not want those image tables.
+
+--  Rather than have clients instantiate System.Rident directly, we have the
+--  single instantiation here at the library level, which means that we only
+--  have one copy of the image tables
+
+with System.Rident;
+
+package Rident is new System.Rident;
