Compiling with the _DECC_V4_SOURCE and _VMS_V6_SOURCE feature- test macros defined enables a local-time-based entry point to the stat function that is equivalent to the behavior before OpenVMS Version 7.0. Compiling with the _USE_STD_STAT feature-test macro defined enables a variant of the stat function that uses an X/Open standard-compliant definition of the stat structure. The _USE_ STD_STAT feature-test macro is mutually exclusive with the _DECC_ V4_SOURCE and _VMS_V6_SOURCE macros.
