 Hi,

 buildbots failed to build GnuTLS 3.3.7. The problem seems to be a missing
 `stdnoreturn.h` header file in `src/libopts/autoopts.h`:

 {{{

 }}}

 The file seems to be part of libopts, the problem seems to have been
 introduced in version 3.3.7. `stdnoreturn.h` is part of the next C
 standard, and seems to be unavailable on older systems. Upstream commit
 that added the change was
 {{{
 commit 3d1a66d4f2716c72b146c6ec1feb2d886e2ef3b3
 Author: Nikos Mavrogiannopoulos <nmav at gnutls.org>
 Date:   Tue Jul 29 22:21:36 2014 +0200

     updated to libopts 5.18.3
 }}}
 I don't see why the new header was necessary, so the proper fix is
 probably removing it completely.

 Please advise upstream about this problem by filing a bug report in their
 bug tracker.
