[4/10] RFC: unconditionally include signal.h
- From: Tom Tromey <tromey at redhat dot com>

- Subject: [4/10] RFC: unconditionally include signal.h
- References: <87obiyzns7.fsf@fleche.redhat.com>
I think that checking for signal.h is pointless, because gdb already
includes it unconditionally in various places -- e.g., utils.c.
This patch removes the useless check and updates the few spots that were
using HAVE_SIGNAL_H.
