Subject [jira] Created: (STDCXX-677) IBM XLC++ 9.0/AIX 5.3] tr1/cstdint limit macros incompatible with system provided C headers

IBM XLC++ 9.0/AIX 5.3] tr1/cstdint limit macros incompatible with system provided C headers
-------------------------------------------------------------------------------------------

                 Key: STDCXX-677
                 URL: https://issues.apache.org/jira/browse/STDCXX-677
             Project: C++ Standard Library
          Issue Type: Bug
          Components: TR1.8 - C Compatibility
    Affects Versions: 4.2.0
            Reporter: Travis Vitek
            Assignee: Travis Vitek
             Fix For: 4.2.1


The following testcase fails to compile because both the C library stdint.h and our tr1/cstdint
headers define defines the C99 limit macros. It looks like we need to avoid defining the macros
if a previous definition already exists. Is that a sufficient solution? What if our defintion
is different for some reason?
