Thanks.

The error message was not helpful at all, there is no `verify_error'
function parameter (it would be nice to be able to set the error message
from these macros).  May I replace it with this?  It's what CHECK_LIST
does, internally, IIUC.

#+begin_src c
  if (!CONSP (x) && !NILP (x))
    error ("gnutls-boot: invalid :verify_error parameter (not a list)");
#+end_src

Thanks
