Speaking about portability we should decide which portability do we mean.

Is such a case you should use portable runtime library. The MS' one is not
very portable. By the way Microsoft says the _sleep() function is obsolete
and deprecated, thus we should avoid using it in a new code.
As for me I would declare macro like this:

#if defined(MSC_VER) || defined(__MINGW32__)
#define HAVE_MS_SLEEP
#endif

#ifdef HAVE_MS_SLEEP
#define sleep_for(seconds)    _sleep( (seconds) * 1000)
#else
#define sleep_for(seconds)    sleep(seconds)
#endif

Surely it doesn't provide extra portability to neither compiler nor clib,
but it makes the program a bit more portable, at least for posix/WIN32
platforms.
