-/* XALLOC -- X's internal memory allocator. Why does it return unsigned
- * long * instead of the more common char *? Well, if you read K&R you'll
- * see they say that alloc must return a pointer "suitable for conversion"
- * to whatever type you really want. In a full-blown generic allocator
- * there's no way to solve the alignment problems without potentially
- * wasting lots of space. But we have a more limited problem. We know
- * we're only ever returning pointers to structures which will have to
- * be long word aligned. So we are making a stronger guarantee. It might
- * have made sense to make Xalloc return char * to conform with people's
- * expectations of malloc, but this makes lint happier.
