all bits zero?

[Georg Wittig]

Does ANSI C require that in the internal representation of the integer constant
``0'' all bits are zero?

What about ``0x0'' (hex.) or ``0000'' (oct.)?

If it IS allowed that in the internal representation not all bits are zero, is
it then possible to write a #if expression that tests if all bits of the integer
constant ``0'' are zero?
