Is signed zero always available?

Both IEEE-754 floats and Decimals support signed zeroes, that is -0.0 and
0.0 are two distinct (but equal) values.

(There is only one int zero: -0 and 0 are the same value.)

Signed Decimal zero should always be available. What about signed float
zero? Are there any platforms where Python is available that don't support
signed zeroes?
