     14  1.3  rillig  * unsatisfiable guard clause.

     16  1.3  rillig  * The C Reference Manual 1978, 2.4.3 "Character constants" does not mention
     17  1.3  rillig  * non-octal digits, therefore this code must have been due to a particular
     18  1.3  rillig  * C compiler's interpretation.  It's even wrong according to the Reference
     19  1.3  rillig  * Manual to interpret '\088' as anything else than a malformed character
     20  1.3  rillig  * literal.

     22  1.3  rillig  * That code has been removed since nobody runs lint in traditional C mode
