+Subject: [PATCH 1/2] Add fallback fopencookie() implementation
+
+In environments where neither fopencookie() nor funopen()
+are implemented, we need to provide a suitable implementation
+of fopencookie() that we can use.
+
+Alex Kanavin: rebased CMakeLists.txt change to apply to latest upstream code.
+
+Upstream-Status: Denied [https://github.com/openSUSE/libsolv/pull/112]
