+Subject: [PATCH 2/2] Link against limited API DLL under Cygwin when abi3 is
+ used
+
+Like with Windows Python, we need to link to a different
+DLL which exports the limited API when using abi3.
+
+This makes pyo3 link against python3.dll instead of
+python3.XY.dll when abi3 is enabled.
+
+Note: The limited API DLL is currently not provided in
+cygwin upstream, but only in MSYS2 for now:
+https://github.com/msys2/MSYS2-packages/pull/5751
