Ummm, unless my memory fails me - it is late in the year, the above is
not a good idea.

Whether you like it or not, baz will be promoted to int by a K&R
compilet, so you would be far better off simply doing:

foo(bar, baz)
	char bar;
	int baz;
{
	short what_i_want = baz;

then all compilers will do the right thing and your code will work as
you expected.
