--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I don't know if this is useful to even to add to -Wsign-conversion.
The documentation is clear here:
Warn for implicit conversions that may change the sign of an integer value,
like assigning a signed integer expression to an unsigned integer variable.
- is just two comp not rather than neg :)
