Subject: [PROPOSED 1/2] Include signal.h in zic
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* zic.c: Include signal.h.  This is needed by the recent addition
of signal-handling code; otherwise zic.c is not portable and
doesn’t compile under Microsoft Windows, and it’s a bit surprising
that it compiled with no problems under GNU/Linux.  Problem
reported by Manuela Friedrich and Steve Shuriff.
