Never mind.  cygipc-1.12 withdrawn.

As Robert kindly pointed out, key_t hasn't changed yet.

But it was supposed to change as of 1.3.11 -- only it didn't, and I 
never noticed 'cause I didn't upgrade...I just assumed that it would 
DEFINITELY have changed in 1.3.12, but I really should have checked. 
Sorry for the false alarm -- but hey, cygipc-1.13 will be *ready to go* 
as soon as key_t DOES change.
