I'm making enemies now,
Where?
but:
If the NIL pointer is represented by another value (like 0xFFFFF780
or such) on a given target platform, the integer conversion from a
_compile-time_ constant 0 literal should still lead to a NIL
representation.
I don't see why, except for compatibility with code built on wrong
assumptions. However, for exactly that same reason nil is unlikely to
ever become something different from pointer(0) in FPC.
Basically that would be the same behaviour as what the C-standard
guarantees.
Does it guarantee that (void*)(0) == NULL?
