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 routine simply takes its argument and converts it to wide string
+   --  format, storing the result in R (1 .. L), with L being set appropriately
+   --  on return. The caller guarantees that R is long enough to accommodate
+   --  the result. This is used in the context of the Wide_Image attribute,
+   --  where the argument is the corresponding 'Image attribute. Any wide
+   --  character escape sequences in the string are converted to the
+   --  corresponding wide character value. No syntax checks are made, it is
+   --  assumed that any such sequences are validly formed (this must be assured
+   --  by the caller), and results from the fact that Wide_Image is only used
+   --  on strings that have been built by the compiler, such as images of
+   --  enumeration literals. 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 argument string. EM
+   --  indicates the wide character encoding method.

+   --  only for codes greater than 16#FF#.
