Fix:	SE009

Problem:
	X11 port fails to compile on Linux (RH6.0) with the following error:

	gcc -ansi -O2 -I../include -I/usr/X11R6/include -I/usr/include -c ../win/X11/Window.c
	../win/X11/Window.c: In function `Redisplay':
	../win/X11/Window.c:113: `caddr_t' undeclared (first use this function)
	../win/X11/Window.c:113: (Each undeclared identifier is reported only once
	../win/X11/Window.c:113: for each function it appears in.)
	../win/X11/Window.c:113: parse error before `event'
	../win/X11/Window.c: In function `Resize':
	../win/X11/Window.c:120: `caddr_t' undeclared (first use this function)
	../win/X11/Window.c:120: parse error before `0'
	make[1]: *** [Window.o] Error 1

Reported by:
	Chris Holck

Notes:	This is due to the fact that the GNU C library does not define
	caddr_t in sys/types.h unless __USE_BSD is defined. In any event,
	the correct type for the third argument of XtCallCallbacks()
	is XtPointer, so this is what we should use.

	Thanks to Chris for help in debugging this problem.

Compatible with:
	Slash'EM 0.0.5E4
