+* Bison now parses C99 lexical constructs like UCNs and
+ backslash-newline within C escape sequences, as POSIX 1003.1-2001 requires.
* --no-line works properly.
the user symbol is used in the reports, the graphs, and the verbose
error messages instead of `$end', which remains being the default.
For instance
- %token YYEOF 0
+ %token MYEOF 0
or
- %token YYEOF 0 "end of file"
+ %token MYEOF 0 "end of file"
