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.

+   --  string literals are not affected, only identifiers. For each set,
+   --  the table in this package gives the mapping of letters to their
+   --  upper case equivalent. Each table thus provides the information
+   --  for building the table used to fold lower case to upper case, and
+   --  also the table of flags showing which characters are allowed in
+   --  identifiers.
+
+   type Translate_Table is array (Character) of Character;
+   --  Type used to describe translate tables
+
+   type Char_Array_Flags is array (Character) of Boolean;
+   --  Type used for character attribute arrays. Note that we deliberately
+   --  do NOT pack this table, since we don't want the extra overhead of
+   --  accessing a packed bit string.
