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 provides a routine for obtaining the version number of the
+--  GNAT compiler used to compile the program. It relies on the generated
+--  constant in the binder generated package that records this information.
+
+--  Note: to use this package you must first instantiate it, for example:
+
+--    package CVer is new GNAT.Compiler_Version;
+
+--  and then you use the function in the instantiated package (Cver.Version).
+--  The reason that this unit is generic is that otherwise the direct attempt
+--  to import the necessary variable from the binder file causes trouble when
+--  building a shared library, since the symbol is not available.
+
+--  Note: this unit is only useable if the main program is written in Ada.
+--  It cannot be used if the main program is written in foreign language.
+
+generic
+package GNAT.Compiler_Version is
+   pragma Pure;
+
+   function Version return String;
+   --  This function returns the version in the form "v.vvx (yyyyddmm)".
+   --  Here v.vv is the main version number (e.g. 3.16), x is the version
+   --  designator (e.g. a1 in 3.16a1), and yyyyddmm is the date in ISO form.
+   --  An example of the returned value would be "3.16w (20021029)". The
+   --  version is actually that of the binder used to bind the program,
+   --  which will be the same as the compiler version if a consistent
+   --  set of tools is used to build the program.
