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.

+! PR fortran/45836
+! The B_TYPE_INSTANCE%SIZERETURN() typebound function used to be rejected on a
+! type mismatch because the function was resolved to A's SIZERETURN instead of
+! B's because of the ambiguity of the SIZERETURN name in the MAIN namespace.
+!
+! Original testcase by someone <ortp21@gmail.com>
