Tested to compile c10t with clang and got a lot of compiler warnings which also overlapped with #270. Didn't run any benchmarks but compiling seems much faster and all my worlds appear to render correctly afterwards. Note that all out-of-tree dependencies were compiled with GCC.

To compile with clang I simply replaced c++ and cc with clang++ and clang in cmakes config gui. Of course you'll have to install clang first.

evildeeds@evil ~/games/minecraft/tools/c10t/c10t-git $ make clean
