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.

+/* Regression test for bug in convoluted situation involving token paste

+   easier to understand if you mentally replace 'struct' with 'A'
+   throughout this file; 'struct' is used only to get the code to compile
+   when preprocessed correctly.

+   The original problem was seen in the Linux kernel and reported by
