consistency with the other scanner helper functions.
 2002-12-01 02:37:56 +00:00
Paul Eggert 6ba5559289 Type clashes now generate warnings, not errors, since it

modifies.  Mention that C99 supports "inline".  Mention that yyerror
traditionally returns "int".

Paul Eggert 16f37b35a5 (Actions after errors): Use an output format 
more similar to that of the Printers and Destructors test.
Test the position of the ';' token too.
(Printers and Destructors): Likewise.
(Printers and Destructors: %glr-parser): Remove for now, to avoid
unnecessarily alarming people when the test fails.
