POSIX stuff is terrible for this sort of thing, but luckily it's often a straightforward fix once you know to look for it. Here's a similar fix for the old Win32 version of the silver searcher: https://github.com/kjk/the_silver_searcher/pull/7

Looks like the active Windows port (https://github.com/k-takata/the_silver_searcher-win32) doesn't have this change, but it's possible Mingw32 or whatever exposes this flag itself now (as it probably should have done originally).
