+# In inttypes.h on HPUX 11, the use of __CONCAT__ in the definition 
+# of UINT32_C has undefined behavior according to ISO/ANSI:
+# the arguments to __CONCAT__ are not macro expanded before the
+# concatination happens so the trailing ')' in the first argument
+# is concatinated with the 'l' in the second argument creating an
+# invalid pp token.  The behavior of invalid pp tokens is undefined.
+# GCC does not handle these invalid tokens the way the HP compiler does.
+# This problem will potentially occur anytime macros are used in the
+# arguments to __CONCAT__.  A general solution to this problem would be to 
+# insert another layer of macro between __CONCAT__ and its use
+# in UINT32_C.  An example of this solution can be found in the C standard.
+# A more specific solution, the one used here, is to change the UINT32_C
+# macro to not used macros in the arguments to __CONCAT__.
