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.

+/* It is a constraint violation for a static function to be declared
+   but not defined if it is used except in a sizeof expression whose
+   result is an integer constant.  In GNU C, we need to consider
+   __typeof__ and __alignof__ as well.  __alignof__ always returns a
+   constant, so static functions can always be used therein.
+   __typeof__ evaluates its argument iff it has variably modified
+   type.  */
