As a temporary workaround on Sun4, you need to
	#define vfork fork

The problem is that on a Sun4, even registers are shared between parent and
child after a vfork, I am told.  I've got a rewritten mypopen(), and several
other patches which I may send out soon, including one to keep shift and pop
from doing a double free when used on @_, and one which lets the idiom
	chop($foo = <STDIN>);
work without trying to input an entire array, sigh.
