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.

+-- DESCRIPTION:
+--     This package provides tailorable entities for a particular
+--     implementation.  Each entity may be modified to suit the needs
+--     of the implementation.  Default values are provided to act as
+--     a guide.
+--
+--     The entities in this package are those which are used exclusively
+--     in tests for Annex G (Numerics).
+-- 
+-- APPLICABILITY CRITERIA:
+--     This package is only required for implementations validating the
+--     Numerics Annex.
+-- 
+-- CHANGE HISTORY:
+--     29 Jan 96   SAIC    Initial version for ACVC 2.1.
