I may well be, but please explain.
src/sysdep.c (at emacs-25 commit c5ee6de21d4b) contains:

#include "gnutls.h"
#if 0x020c00 <= GNUTLS_VERSION_NUMBER && !defined WINDOWSNT
# include <gnutls/crypto.h>
#else
# define emacs_gnutls_global_init() Qnil
# define gnutls_rnd(level, data, len) (-1)
#endif

How can this build properly on a non-Windows system which does not
contain an installed "gnutls.h" header ?
