I'm working on replacing some assembly code with C, and I'd like to redo
a timer-tick interrupt routine.  In order to do this, I need to do a
stack switch.  I know I can do this in Turbo C:

    unsigned oldSS, oldSP, newSS, newSP;
    void interrupt stackswitch(void)
    {
	disable();
	oldSS = _SS;
	oldSP = _SP;
	_SS = newSS;
	_SP = newSP;
    }

How do I do the equivalent in Microsoft C 5.1?  (_Must_ I use assembly?
How primitive!  :-)
