I'm hesitant to agree.  Perhaps a we should base the absence on win32
version?  Perhaps we should, in the case of _sleep(), supply a function
that works as we expect it to.  I searched for _beep and MSDN and didn't
find a reference.  This is indication that you are correct.  We probably
should let the Community decide.

I think `_sleep' etc. should be kept but `sleep' etc. should be removed.

I am also wondering whether we should add a UNIX-like `sleep'. This idea 
is attractive, and some Win32 compilers (like Digital Mars) already 
provides such a function (but DMC does not provide `_sleep'). However, 
if (old) MSVC compatibility is to be kept, and `_sleep' is to be 
retained, then a `sleep' having different semantics from `_sleep' might 
be confusing. So....
