a-direct.adb (Duration_To_Time, [...]): New Unchecked_Conversion functions.
2006-02-13 Vincent Celier <celier@adacore.com>
* a-direct.adb (Duration_To_Time, OS_Time_To_Long_Integer): New
Unchecked_Conversion functions.
(Modification_Time): Use direct conversion of OS_Time to Calendar time
when OpenVMS returns False.
* a-dirval-mingw.adb, a-dirval-vms.adb, a-dirval.ads,
a-dirval.adb (OpenVMS): New Boolean function
