From: David CARLIER <devne...@gmail.com>
Regularize our handling of <sys/signal.h>: currently we include it in
osdep.h, but only for OpenBSD, and we include it without an ifdef
guard in a couple of C files. This causes problems for Haiku, which
doesn't have that header.
Instead, check in configure whether sys/signal.h exists, and if it
does then always include it from osdep.h.
