I've been doing my own cleanup of bignum.c using cl 14 only to discover warnings like this:

bignum.c(836) : warning C4146: unary minus operator applied to unsigned type, result still unsigned

Sure enough the (now ANSI) source looks like this:

unsigned long rb_big2ulong_pack(VALUE x)
{   
   unsigned LONG_LONG num = big2ulong(x, "unsigned long");

   if(!RBIGNUM(x)->sign)
      return -num; /* Uh...what? */

   return num;
}

These only show up in MS VC++ if you compile with warnings on (I'm running at -W3). They do NOT show up with either gcc 3.x or SSC 11 with full warnings on (last I checked).

The bignum source code is littered with this crap, btw.
