* parse.y: yyparse #defines moved from intern.h

* ruby.c (proc_options): access prefixed "ruby_yydebug".

* applied modifies to pacify some of gcc -Wall warnings.

* parse.y (arg): no more ugly hack for "**", so that "-2**2" to be
  parsed as "(-2)**2", whereas "- 2**2" or "-(2)**2" to be parsed
  as "-(2**2)".

* parse.y (yylex): '-2' to be literal fixnum. [new]

* time.c (time_succ): new method for Range support.

* time.c (time_arg): nil test against v[6] (usec).
