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.

+! Tests patch for PR24158 - The module would compile, in spite
+! of the recursion between the derived types. This would cause
+! an ICE in the commented out main program. The standard demands
+! that derived type components be already defined, to break
+! recursive derived type definitions.
