Author : Nick Mathewson
Date : 2009-04-23 00:21:23
Hash : df0617f2
Message : Use signal.h, not sys/signal.h. This is patch 2673214 from mmadia. It is correct, since we unconditionally include signal.h in many other places, and only sometimes include sys/signal.h. It is necessary to compile on Haiku, I'm told. svn:r1228
