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.

+ * Creating a type variable requires resolving the appropriate type.
+ * This may involve resolving other classes as a side effect (e.g.

+ * involve resolving the bounds. Repeated creation has no effect; an

+ * instances must be <code>equal()</code> to each other.
