Warning and Error signals print a message; Error also terminates the compilation after the current phase completes.  FatalError is like Error, except that it immediately terminates the compilation.  InternalError is used to report internal Saffron errors.  It immediately terminates the compilation.  All of these signals are handled by the driver (SaffronDriver.mesa).An alternative which avoids explicitly signalling.These procedures are called by the driver to report errors.Э╩f  Ш ЩIcodeЩ<KЪЬ&╧kЩ)KЪЬ5ЭЩ8KЩ ЧЪЭ	Ш	JЪЭЬЭЬЭЬШJЪЬЭЬЭЬШKШ KЩ ЧЪ╧nЬЭЬЭЬЭШ/KШ KЪЬ╧bЬEЯЬЯЬЯЬEЯ
