b3c0db218d Remove "EOF-newline" lexer hack 
In preparation for an upcoming change
Makes for nicer error messages, complaining about EOF instead of newlines
The hack had to be kept for the lexer raw mode to avoid a bug;
see the relevant code comment for more info.

93d83e17dc Don't override bison's internal 'yytnamerr' function

aa27e714d4 Make Bison version detection more portable

- `mawk` does not fully support POSIX EREs (regexes),
