Subject: [PATCH 1/4] misc: quiet minor compiler errors
Several compiler errors are quieted:
- zero-length gnu_printf format string
- unused variable
- uninitalized variable (though it isn't actually used for anything)
- use of stat64/open64 on OSX (deprecated API)
Signed-off-by: Andreas Dilger <adilger@...mcloud.com>
