Yes indeed. I fixed this in the master branch, as of
https://gitlab.com/openconnect/openconnect/-/commit/7512698217c4104aade7a2df669a20de68f3bb8c

As I noted in the commit message, the lack of a backwards-compatible
constant name (GNUTLS_NO_EXTENSIONS) appears to have been an
inadvertent omission in GnuTLS 3.8.1, and should be fixed in the next
release of GnuTLS due to a subsequent commit.
