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.

+     iexport_proto	Marks a function to be exported, but with the 
+			understanding that it can be used inside as well.
+

+			Unfortunately, some systems can't play the hidden
+			symbol renaming trick on data symbols, thanks to
