new class for parser state * oct-parse.yy, parse.h (octave_parser): New class (curr_parser): New global variable. * oct-parse.yy (eval_string, parse_fcn_file): Save curr_parser on unwind_protect stack. Create new curr_parser and arrange for it to be cleaned up. * toplev.cc (main_loop): Likewise. * input.cc (get_debug_input): Likewise.
