Both os-win32.h and os-posix.h include system header files. Instead of having osdep.h include them inside its 'extern "C"' block, make these headers handle that themselves, so that we don't include the system headers inside 'extern "C"'. This doesn't fix any current problems, but it's conceptually the right way to handle system headers.
