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.

+! { dg-do run }
+! Test the fix for PR43291, which was a regression that caused
+! incorrect type mismatch errors at line 46. In the course of
+! fixing the PR, it was noted that the dynamic dispatch of the
+! final typebound call was not occurring - hence the dg-do run.
