+Description: Fix gnutls FTBFS
+ A patch we have been backporting as part of #1982841 prevents compilation of
+ gnutls and this restores it. Patch is from upstream.
+Author: Adrien Nader <adrien.nader@canonical.com>
+Origin: backport, https://github.com/p11-glue/p11-kit/pull/424
+Bug: https://github.com/p11-glue/p11-kit/issues/419#issuecomment-1259353294
+Bug-Ubuntu: https://bugs.launchpad.net/ubuntu/+source/p11-kit/+bug/1991067

+From 4276a4a6d2a480606ece19cedaddfeec731ebb1e Mon Sep 17 00:00:00 2001

+Subject: [PATCH] pkcs11-gnu: Enable testing with <p11-kit/pkcs11x.h>
+
+This ensures that programs using <p11-kit/pkcs11x.h> can be compiled
+with CRYPTOKI_GNU.  The previous coverage was partial as pkcs11-gnu.c
+didn't include "pkcs11x.h" and Meson didn't supply -DCRYPTOKI_GNU=1.
