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.

+   --  General note on universal fixed. In the routines below, a fixed-point
+   --  type is always a specific fixed-point type or universal real, never
+   --  universal fixed. Universal fixed only appears as the result type of a
+   --  division or multiplication and in all such cases, the parent node, which
+   --  must be either a conversion node or a 'Round attribute reference node,
+   --  has the specific type information. In both cases, the parent node is
+   --  removed from the tree, and the appropriate routine in this package is
+   --  called with a multiply or divide node with all types (and also possibly
+   --  the Rounded_Result flag) set.
