coverity/100248: Operands don't affect result: HI.

Browse Source 
Problem    : Operands don't affect results (CONSTANT_EXPRESSION_RESULT).
Diagnostic : Harmless issue.
Rationale  : n >= LONG_MIN, n being intmax_t, is always true for
             architectures where sizeof(intmax_t) == sizeof(long).
Resolution : Add sizes check.
