Lasly, (sorry for not collecting all thoughts first), suspect the problem may be that
~ is being considered as being analogous to an arithmetic -, which it shoudn't be;
therefore ~(any constant value >= 0) should be compatible with either signed or unsiged.
although  -(any constant value >= 0) should be compatible with only signed witout a cast.
(as ~ is a bit-wise operation, not a arithmetic one, otherwise one couldn't even specify:
 (unsigned)x = (unsigned)x & 0x3; without a cast, likely generating tons of useless warnings)
