Pull up revision 1.4 (requested by bouyer in ticket #35):
npxintr(): this function does the right thing if we don't try to clear
the interrupt latch (which is probably done by the hypervisor, linux/xen
doesn't do it either). Now the "fputest" configure test from pkgsrc/math/yorick
works as expected.
Thanks to Christian Limpach for the hint.
