The problem is that Visual C++ emits function calls for extended
arithmetic that aren't stdcall.  If C code performs a divide nearby a
mod, for example, it can emit a call to _aulldvrm, which returns two 64
bit values in four 32 bit registers.  The shift functions pass the shift
width in cl, because that's what the CPU would normally use, etc.
