* data/glr.c (YYFPRINTF): Always define it, not only when YYDEBUG (yyuserAction, yyreportAmbiguity): `Use' all the arguments. (yyremoveDeletes): `yyi' and `yyj' are size_t. Use YYFPRINTF when under if (YYDEBUG) to avoid empty `if' bodies. (yyaddDeferredAction): static. (yyglrReduce): yyi, yyk, amd yyposn are size_t. (yyreportParseError): yyprefix is const. yytokenp is used only when verbose. (yy__GNUC__): Replace with __GNUC__. (yypdumpstack): yyi is size_t. (yypreference): Un-yy local variables and arguments, to avoid clashes with `yyr1'. Anyway, we are not in the user name space. (yytname_size): be an int, as is compared with ints. * tests/testsuite.at (AT_COMPILE, AT_PARSER_CHECK): New. Use them. * tests/cxx-gram.at: Use quotation to protect $1. Use AT_COMPILE to enable warnings hunts. Prototype yylex and yyerror. `Use' argc. Include `string.h', not `strings.h'. Produce and prototype stmtMerge only when used. yylex takes a location.
