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 file is the C file that corresponds to the Ada package spec

+   This package contains routines for handling the strings table which is
+   used to store string constants encountered in the source, and also those
+   additional string constants generated by compile time concatenation and
+   other similar processing.
+
+   A string constant in this table consists of a series of Char_Code values,
+   so that 16-bit character codes can be properly handled if this feature is
+   implemented in the scanner.
+
+   There is no guarantee that hashing is used in the implementation. This
+   means that the caller cannot count on having the same Id value for two
+   identical strings stored separately.
+
+   The String_Id values reference entries in the Strings table, which
+   contains String_Entry records that record the length of each stored string
+   and its starting location in the String_Chars table.  */
