Merge branch 'mr/opt-set-ptr'

OPT_SET_PTR() implementation was broken on IL32P64 platforms;
it turns out that the macro is not used by any real user.

* mr/opt-set-ptr:
  parse-options: remove unused OPT_SET_PTR
  parse-options: add cast to correct pointer type to OPT_SET_PTR
  MSVC: fix t0040-parse-options crash

-	Introduce a boolean option.
-	If used, set `ptr_var` to `ptr`.

 `OPT_STRING(short, long, &str_var, arg_str, description)`::
 	Introduce an option with string argument.
 	The string argument is put into `str_var`.
