1435 * In inttypes.h on HPUX
11, the use of __CONCAT__ in the definition

/ANSI
:
1437 * the arguments to __CONCAT__ are not macro expanded before the
1438 * concatination happens so the trailing
')' in the first argument
1439 * is concatinated with the
'l' in the second argument creating an

1442 * This problem will potentially occur anytime macros are used in the
1443 * arguments to __CONCAT__. A general solution to this problem would be to
1444 * insert another layer of macro between __CONCAT__ and its use
1445 * in UINT32_C. An example of this solution can be found in the C standard.
1446 * A more specific solution
