Debian built with clang

Description of the project: During the last couple years, important efforts have been produced to build Debian with Clang instead of gcc. Clang is now features completed and compiles most of the archive. However, clang being stricter than gcc, it rejects a lot of packages.

The goal of this project is to patch all packages failing to build with clang. Forwarding to upstream the patches will be part of the project (even if it is usually the responsibility of the Debian maintainer).

Many bugs have been already reported under the clang-ftbfs flag.
