+From: Naveen M K <naveen521kk@gmail.com>
+Date: Sat, 5 Aug 2023 14:10:27 +0530
+Subject: [PATCH 141/N] Search DLLs only on paths added using
+ `add_dll_directory()`.
+
+This is the default behavior on upstream Python. We previously
+reverted this behavior because it broke some use cases.
+
+The old behavior can be restored by setting the environment variable
+PYTHONLEGACYWINDOWSDLLLOADING to 1.
+
+Fixes https://github.com/msys2-contrib/cpython-mingw/issues/48
+Also fixes https://github.com/msys2-contrib/cpython-mingw/issues/141
