I can't recreate the UnixFileTest test failure (I'm running with the IBM
Java 6 VME):
[junit] Running org.apache.harmony.luni.tests.java.io.UnixFileTest
    [junit] Tests run: 1, Failures: 0, Errors: 0, Time elapsed: 0.503 sec

UnixFileTest is not stable for me, it failed intermittently, suppose not related 
 to this issue.

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] hyfiletext.c:234: warning: ignoring return value of 'wctomb',
declared with attribute warn_unused_result
     [exec] hyosdump.c:86: warning: ignoring return value of 'chdir',
declared with attribute warn_unused_result
     [exec] linux/../hysl.c:306: warning: ignoring return value of
'mbtowc', declared with attribute warn_unused_result
