in C, as you know, integer assignment is subject to integer promotion.
If the LHS is wider, the RHS is widened to match. The specification is
much more precise, of course, but that's the effect.
There's nothing invalid of ambiguous about:
long L = '\0';
It is the same as
long L = 0L;
The same is true for pointers.
