Well I have a preliminary implementation, which now builds fine but
unfortunately when building software dependent on it I get a C compile
error which isn't caught at compilation-time:

 ecl-server2.c:851: error: too few arguments to function 'si_posix_signal_action'

Similarily to the earlier problems with catch-signal.

I won't be able to resume working on it tonight, and unfortunately have
no clue right now what I missed.  I'm unsure that the prototypes I
added to external.h are right, or the proclamations.

So I here attach what I have so far in case it's obvious to you; I
might be able to resume working on it this weekend.
