+Subject: [PATCH] fix compatibility with libressl
+
+These functions are exported by libcrypto from libressl, due to its
+similar OpenBSD compatibility layer, but they are not present in any
+header files. Thus, while we can use the existing compiled function,
+and do not need to provide our own, we do need to provide the prototype
+for it.
+
+This avoids implicit function declarations and the resulting crashes due
+to pointer truncation.
+
+The patch is based on an equivalent patch for OpenSSH from
+https://bugzilla.mindrot.org/show_bug.cgi?id=2465
+Also see
+https://github.com/libressl-portable/portable/issues/109
+
+Fixes #691

+inet_net_pton is already compiled, but no prototype is provided.
+res_hnok is provided by the compatibility layer in libasr.
