* keylist.c (list_keyblock_colon): Don't include validity values when

Browse source 
listing secret keys since they can be incorrect and/or misleading.  This
is a temporary kludge, and will be handled properly in 1.9/2.0.

* signal.c (init_one_signal, pause_on_sigusr, do_block): Only use
sigprocmask() if we have sigset_t, and only use sigaction() if we have
struct sigaction.  This is for Forte c89 on Solaris which seems to define
only the function call half of the two pairs by default.
(pause_on_sigusr): Typo. (do_block): If we can't use sigprocmask() and
sigset_t, try to get the number of signals from NSIG as well as MAXSIG,
and if we can't, fail with an explanation.
