compiling xview on Roell's port

[David Hobbs]

Just wanted to thank everyone for their suggestions on compiling xview
programs under Roell's port.  It turns out that (other than linking in
the correct libraries) if types.h is included several times, which it
is, syntax errors result.  I just had to add a line to my types.h
like:
	#ifndef __sys_types_h
	#define __sys_types_h

		.
		.
		.

	#endif

This could come in handy for the next person that runs into the same problems
that I had.  Again, thanks everyone for your suggestions!
