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.

+   --  using the internal compiler escape sequence convention (defined in

+   --  of type String. In the context of the Wide_Value attribute, the
+   --  argument is the original attribute argument, and the result is used
+   --  in a call to the corresponding Value attribute function. If the method
+   --  for encoding is a shift-in, shift-out convention, then it is assumed
+   --  that normal (non-wide character) mode holds at the start and end of
+   --  the result string. EM indicates the wide character encoding method.
+   --  Note: in the WCEM_Brackets case, we only use the brackets encoding
+   --  for characters greater than 16#FF#. The lowest index of the returned
+   --  String is equal to S'First.
