[PATCH v4 0/3] Take four on fixing OPT_SET_PTR issues

Patches summary:
1. Fix initial issue (incorrect cast causing crash on 64-bit MSVC)
2. Improve OPT_SET_PTR to prevent same errors in future
3. Purge OPT_SET_PTR away since nobody uses it

*Optional* patch №3 is separated from №1 and №2 so that if someone someday decides to return OPT_SET_PTR back by reverting №3, it will be returned in a sane state.

Decision of (not) merging №3 is left as an exercise to the reader due to my insufficient knowledge of accepted practices in Git project.

Marat Radchenko (3):
  MSVC: fix t0040-parse-options crash
  parse-options: add cast to correct pointer type to OPT_SET_PTR
  parse-options: remove unused OPT_SET_PTR
