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.

+! This tests the fix for PRs 26834, 25669 and 18803, in which
+! shape information for the lbound and ubound intrinsics was not
+! transferred to the scalarizer.  For this reason, an ICE would
+! ensue, whenever these functions were used in temporaries.
+!
+! The tests are lifted from the PRs and some further checks are
+! done to make sure that nothing is broken.
