> 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:

>      [exec] hyosdump.c:86: warning: ignoring return value of 'chdir', declared with attribute warn_unused_result
