div.c and other questions

I inserted the code snip into a different project with different
headers,compiler settings, etc. and got this message:

error C2513: 'int' : no variable declared before '='

I've done some research and this problem has popped up before on at least
one other project and they just patched their code.

Other compilers besides MSVC recognize these non-ANSI extensions:

There's even a GNU compiler for some platform claiming to recognize near and

It is a hold over from DOS, there's no reason for it, it doesn't apply to
x-86, etc.  Rather than lament the idiosyncrasies of MSVC, let's just agree
to change the variable name to whatever is appropriate and move on.

Well, since Brian tells us the problem is only with MSVC++6, there is no
point in my trying since I have only MSVC++7 here.
