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.

+! { dg-do compile }
+! One of the tests of the patch for PR30068.
+! Taken from comp.lang.fortran 3rd December 2006.
+!
+! Although the generic procedure is not referenced and it would
+! normally be permissible for it to be ambiguous, the USE, ONLY
+! statement is effectively a reference and is invalid.
