Subject: [PATCH] Shim for renaming of GNUTLS_NO_EXTENSIONS in GnuTLS v3.8.1
The constant `GNUTLS_NO_EXTENSIONS` was renamed in
https://gitlab.com/gnutls/gnutls/-/commit/a7c4a04e (released in v3.8.1), and
then a backwards-compatibility shim was belatedly added in
https://gitlab.com/gnutls/gnutls/-/commit/abfa8634, which has not yet been
released.
We need to re-add the constant ourselves in order to build correctly with
GnuTLS v3.8.1. This should fix
https://gitlab.com/openconnect/openconnect/-/issues/650.
Upstream-Status: Backport [https://git.infradead.org/users/dwmw2/openconnect.git/commit/7512698217c4104aade7a2df669a20de68f3bb8c]
