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 contains the routines for Ada.Wide_Wide_Text_IO.Decimal_IO
+--  that are shared among separate instantiations of this package. The
+--  routines in the package are identical semantically to those declared
+--  in Wide_Wide_Text_IO, except that default values have been supplied by the
+--  generic, and the Num parameter has been replaced by Integer or
+--  Long_Long_Integer, with an additional Scale parameter giving the
+--  value of Num'Scale. In addition the Get routines return the value
+--  rather than store it in an Out parameter.
