2010-09-09 Robert Dewar <dewar@adacore.com> * sinput-p.ads: Minor comment update. 2010-09-09 Arnaud Charlet <charlet@adacore.com> * s-tpobop.adb, s-taenca.adb (Wait_For_Completion_With_Timeout): Reset Entry_Call.State if needed so that the call is marked as cancelled by Check_Pending_Actions_For_Entry_Call. (Timed_Protected_Entry_Call): Adjust calls to Defer/Under_Abort, since this procedure may be called from a controlled operation (Initialize/Finalize). 2010-09-09 Vadim Godunko <godunko@adacore.com> * impunit.adb: Correct spelling of package's name in the comment.
