verified gcc-4.6.4.tar.bz2.sig;
imported gcc-4.6.4 source tree from verified upstream tarball.

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

+/* Test "ignore redundant include" facility.

+   -H is used because cpp might confuse the issue by optimizing out
+   #line markers.  This test only passes if the headers is read
+   twice.
+
+   The disgusting regexp in the dg-error line, when stuck into
+   dg.exp's compiler-output regexp, matches the correct -H output and
+   only the correct -H output.  It has to be all on one line because
+   otherwise it will not be interpreted all in one unit.  */
