From memory, the possibility of requiring texinfo 4.0 as part of
building GDB 5 was considered and rejected :-(

This would be my fault.  Thanks.

Note that when I wrote this patch, I did before-and-after testing
against the gdb test suite with no regressions.  It would be nice if
there were test cases for this code.

I've just committed the change below.  (This change was for AIX 4.3.)

	* gdb.base/pointers.c (usevar): New function.
	(main): Make sure that global variables v_int_pointer2, rptr,
	and y are all referenced someplace in the program by calling
	usevar() on them.  [Some linkers delete symbols which are
	never referenced.  The space remains, but there's no way to
	get a (symbolic) handle on the variable from the debugger.]
