Building in release mode fails with gcc version 4.3.3
-----------------------------------------------------

                 Key: HARMONY-6266
                 URL: https://issues.apache.org/jira/browse/HARMONY-6266
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
         Environment: Linux 32 running 2.6.28-11-generic #42-Ubuntu
            Reporter: Catherine Hope
            Priority: Minor
         Attachments: patch.txt

Building in release mode (the default for building Harmony  Select) will currently fail on
gcc version 4.3.3 as warnings are treated as errors and that compiler version is more strict
in regards to things like not checking return codes of library functions.  The files affected
are:
