From 58887d58c6addd2ed727d57520c6c4629d59f89a Mon Sep 17 00:00:00 2001 From: Andrew Dunstan Date: Mon, 25 Apr 2022 15:02:13 -0400 Subject: [PATCH] Inhibit mingw CRT's auto-globbing of command line arguments For some reason by default the mingw C Runtime takes it upon itself to expand program arguments that look like shell globbing characters. That has caused much scratching of heads and mis-attribution of the causes of some TAP test failures, so stop doing that. This removes an inconsistency with Windows binaries built with MSVC, which have no such behaviour. Per suggestion from Noah Misch. Backpatch to all live branches.
