(yyparse): Call YYABORT instead of YYERROR, due to last change in output_ltype. 1988-09-05 Richard Stallman <rms@sugar-bombs.ai.mit.edu> * Makefile: New variable LIBS. Alternatives for USG. * src/conflicts.c [USG]: Define bcopy. * src/symtab.c [USG]: Include string.h instead of strings.h. * src/conflicts.c [sparc]: Include alloca.h. 1988-08-02 Richard Stallman <rms@sugar-bombs.ai.mit.edu> * src/reader.c (parse_token_decl): Ignore commas. 1988-06-25 Richard Stallman <rms@sugar-bombs.ai.mit.edu> * src/reader.c (output_ltype): Make YYERROR yacc-compatible (like YYFAIL). 1988-06-24 Richard Stallman <rms@sugar-bombs.ai.mit.edu> * src/getargs.c (getargs): -t sets debugflag. Eliminate upper case duplicate options. * src/output.c (output): If debugflag, output `#define YYDEBUG'. 1988-05-26 Richard Stallman <rms@frosted-flakes.ai.mit.edu> * src/allocate.c (mallocate): New name for `allocate' (which loses in VMS). Calls changed in LR0.c, conflicts.c, symtab.c, new.h. * src/getargs.c (getargs): If argv[0] is "yacc", set fixed_outfiles. 1988-05-17 Richard Stallman <rms@frosted-flakes.ai.mit.edu> * src/conflicts.c: Declare alloca. * src/reader.c: Declare realloc. * src/warshall.c (TC): Fix one arithmetic op that was omitted last time. 1988-05-05 Richard Stallman <rms@frosted-flakes.ai.mit.edu> * src/bison.simple: Conditionalize most refs to yylsp on YYLSP_NEEDED. * src/reader.c (copy_guard, copy_action): Notice if `@' is used. (reader): If it was, output `#define YYLSP_NEEDED'. 1988-04-18 Richard Stallman <rms@rice-krispies.ai.mit.edu> * src/bison.simple: New variable yynerr counts calls to yyerror. * src/lex.c (lex, case '='): Update lineno when skipping a newline. * src/reader.c (parse_expect_decl): ungetc the char that ends the number; don't read any further. This handles multi-line comments right and avoids incorrect lineno. * src/reader.c: Delete duplicate decl of symval. * src/warshall.c (RTC, TC): Cast ptrs to char *, not unsigned, for arith.
