Change #256543

Comments

windows: `USE_WINSOCK` to guard winsock2 code (where missing)
Replacing `_WIN32`.

Also:
- tool_doswin: guard possibly non-portable socket code with
  `USE_WINSOCK`. The socket is cast to `HANDLE` and passed to
  win32 API `SetStdHandle(STD_INPUT_HANDLE, ...)`.
- lib/setup-win32.h: move `#undef`s before their `#define` pair.

Closes #20455
