KWIML: Teach INT about broken UINT32_C on old HP 

Old HP inttypes.h defines UINT32_C as:

 #define __CONCAT__(_A,_B) _A ## _B
 #define __CONCAT_U__(_A) _A ## u
 #define UINT32_C(__c) __CONCAT__(__CONCAT_U__(__c),l)

The __CONCAT__ macro does not delay concatenation for an extra level so
standard preprocessor implementations like GNU complain that they cannot
concatenate the ")" and "l".
