2000-06-26 Joseph S. Myers <jsm28@cam.ac.uk>
* c-decl.c (grokdeclarator): Don't warn about `long long' in C99.
Make warnings about implicit int be pedwarns in C99. Don't warn
about duplicate type qualifiers in C99.
(start_function): Make warning about implict int return type be a
pedwarn in C99.
* c-lex.c (yylex): Don't warn about `long long' in C99.
* c-typeck.c (c_expand_return): In C99, always pedwarn about
`return' with no value in function returning non-void.
2000-06-26 Richard Henderson <rth@cygnus.com>
* c-typeck.c (pedwarn_c99): New.
* diagnostic.c (verror, vwarning, vpedwarn): Export.
* toplev.h: Prototype them.
