Debian Package rebuild

gobjc is the ObjC runtime of GCC. Therefor clang does not include gobjc headers.

libobjc2 is the free drop-in replacement for the GCC runtime by the GNUstep project. It is meant to be used together with clang.
libobjc2 supports the following features above and beyond the GCC runtime (copied from the project's README, MIT license):

• The modern Objective-C runtime APIs, initially introduced with OS X 10.5.
• Blocks (closures).
• Synthesised property accessors.
• Efficient support for @synchronized()
• Type-dependent dispatch, eliminating stack corruption from mismatched selectors.
• Support for the associated reference APIs introduced with Mac OS X 10.6.
• Support for the automatic reference counting APIs introduced with Mac OS X 10.7

There are no official Debian packages for libobjc2 yet. Packaging work in progress is done as part of the Nextspace project.

The wish #680784 may be removed as it does not seem to provide a sufficient solution.
