This allows for + the use of YYPARSE_PARAM, by having the output that checks for + YYPARSE_PARAM to be defined come after the C code block in the + definitions section of a yacc file. + + Implement support for YYLEX_PARAM, similar to bison. This is useful for + support for building reentrant lexers with flex. + + Fix a compatibility issue with bison's pure-parser option. Bison + defines yylex as sending at least one parameter, &yylval, as the first + parameter and doesn't seem to have an easy way to remove that parameter. + This on the other hand is rather convenient to support saving to yylval + from flex when building reentrant lexers and parsers. + + Add support for the %parse-param and %lex-param directives used in + bison. This change bears some similarity to NetBSD's changes to byacc + at http://www.mail-archive.com/source-changes-full@netbsd.org/msg08143.html + + Bison allows for POSIX yacc emulation via a yacc directive in the yacc + file, and also via a command line switch. Implement this feature as a + no-op for byacc, since byacc is designed to be POSIX yacc compatible + anyway. This allows for better compatibility with yacc sources written + for bison. + +2010-06-07 Thomas E. Dickey <tom@invisible-island.net> + + * VERSION: bump to 2010/06/07 + +2010-06-06 Thomas E.
