There is a bug in the distributed version of xedit which causes a core
dump on the sparc (SUN4).

Below is a simple fix. 

183c183,184
<     XtGetValues(toplevel, args, XtNumber(args));
---
>     /*XtGetValues(toplevel, args, XtNumber(args));*/
>     XtGetValues(toplevel, args, 2);

The problem occurs because XtNumber returns 3 (since that is the size of the
array) but only 2 values are initialised. On all? machines except the
sparc, the stack at that point happens to be 0. On the sparc, the values
are not 0, and so invalid values result, causing a segmentation violation.
