value to signal that the operation of retrieving the element from the free list failed. However in this case the returned pointer was set to NULL as well, so the error code was redundant. Moreover, this was a continuous source of warnings when the picky mode is on. The attached parch remove the rc argument from the OMPI_FREE_LIST_GET and OMPI_FREE_LIST_WAIT macros, and change to check if the item is NULL instead of using the return code. This commit was SVN r28722.
