Either that, or I need to add something that allows XSHM to be disabled
from the compile command.  Yes, that's the solution -- I'll add a
test for NO_XSHM (along with the current test for HP-UX that also
disables shared memory ;) and then you just need to add -DNO_XSHM to
the CFLAGS.

Look near the beginning od sqXWindow.c and you'll see where you need to
change

	#ifdef HPUX
into
	#if defined(HPUX) || defined(NO_XSHM)

(or somesuch).  Bye,

Ian
