It's too confusing only if you're easily confused.  Cast your d*mn pointers
properly (like "lint" tells you to do) and lots of problems go away.
If you absolutely *need* a pointer that can point to any one of ten
things, and a union of ten pointer types won't do, use "char *" (or "void *"
if/when it appears in the ANSI standard).
