Not so wonderful. Lots of warnings are disabled:

  add_llvm_definitions( -wd4146 -wd4503 -wd4996 -wd4800 -wd4244 -wd4624 )
  add_llvm_definitions( -wd4355 -wd4715 -wd4180 -wd4345 -wd4224 )
  add_llvm_definitions( -wd4351 )

It's very likely that some of those warnings are really useful (i.e. are
hinting at bugs.) OTOH, keeping LLVM warning-free for VC++ and gcc at
the same time looks like a never-ending uphill battle.
