Forward declaration of a enum is a non-standard extension and is not supported by MSVC. Use an int instead.
Abstract the use of the int/enum rte_cpu_flag_t in function parameter lists by re-typdefing the enum rte_cpu_flag_t to the rte_cpu_flag_t identifier. Remove the use of __extension__ on function prototypes where rte_cpu_flag_t appeared in parameter lists, it is sufficient to have the conditionally compiled __extension__ at the non-standard forward declaration site.
