You missed de Bra's point.  On the 386, the integer constant written
"2147483648" has type (unsigned long int), as specified in 3.1.3.2
Semantics.  The constant expression consisting of "-" followed by
such a numeric string" therefore also has type (unsigned long int).
Since 2.2.4.2.1 specifies that the values of the macros shall be
replaced by expressions that have the same type as would an expression
that is an object of the corresponding type converted according to the
integral promotions, the types should be (int) and (long int),
respectively; thus the implementation is providing incorrect types.
