Compilation with Clang 3.0 (which is available in Debian/stable) fails, mostly due to some scoping and naming inconsistencies which weren't detected by GCC. At some instances, Clang seems to have problems to figure out a perfectly valid type definition; these can be resolved by more explicit typing (which is preferrable anyway)
