ctypes 0.3 and earlier contains an interface-definig bug: its ptr_of_raw_address accepts Int64 and not Nativeint. ctypes 0.4 was not released during the 3.6 cycle, and because of that, LLVM 3.6 was released with ctypes 0.3 as a dependency, which now breaks the build on modern ctypes. Unbreak. llvm-svn: 240882
