With GCC 4.4.7 from CentOS 6.5, the following errors arise:

lib/librte_pmd_ixgbe/ixgbe_rxtx.c: In function ?ixgbe_dev_rx_queue_setup?:
lib/librte_pmd_ixgbe/ixgbe_rxtx.c:2509: error: missing initializer
lib/librte_pmd_ixgbe/ixgbe_rxtx.c:2509: error: (near initialization for 
?dev_info.driver_name?)

lib/librte_pmd_ixgbe/ixgbe_rxtx.c: In function ?ixgbe_set_rsc?:
lib/librte_pmd_ixgbe/ixgbe_rxtx.c:4072: error: missing initializer
lib/librte_pmd_ixgbe/ixgbe_rxtx.c:4072: error: (near initialization for 
?dev_info.driver_name?)

lib/librte_pmd_ixgbe/ixgbe_rxtx.c: In function 
?ixgbe_recv_pkts_lro_single_alloc?:
lib/librte_pmd_ixgbe/ixgbe_rxtx.c:1479: error: ?next_rsc_entry? may be used 
uninitialized in this function
lib/librte_pmd_ixgbe/ixgbe_rxtx.c:1480: error: ?next_rxe? may be used 
uninitialized in this function
