This patch fixes a bug in which pragma Ignore_Pragma(Interface); is illegal, except in Ada 83 mode. It should be legal in all modes. The following test should compile quietly. -- gnat.adc pragma Ignore_Pragma(Interface); -- legal_interface.ads package Legal_Interface is procedure Interface_Or_Not; pragma Interface (Esperanto, Interface_Or_Not); -- The pragma should be ignored, so the body of Interface_Or_Not is legal, -- and the fact that Esperanto is not a supported language is irrelevant. end Legal_Interface; -- legal_interface.adb package body Legal_Interface is procedure Interface_Or_Not is begin null; end Interface_Or_Not; end Legal_Interface; Tested on x86_64-pc-linux-gnu, committed on trunk 2017-04-25 Bob Duff <duff@adacore.com> * par-ch2.adb, scans.ads, scn.adb: Do not give an error for reserved words inside pragmas. This is necessary to allow the pragma name Interface to be used in pragma Ignore_Pragma. * par.adb: Minor comment fix.
