Curiously, I implemented init_pair() and it turns out that gcc sign extends
each parameter before using it.
So this problem does depend on what's going on with init_pair's implementation.

gcc, however, does indeed set the upper 16 bits to zero. I suppose dmd should
behave the same way, regardless of the spec.

A smaller version:
extern(C) int init_pair(short pair, short f, short b);
void test() { init_pair(1, 2, 3); }
which generates:
_D4testQfFZv:
pushRBP
mov RBP,RSP
mov 8D
