Make inclusion of <signal.h> conditional on SIG_DFL not being already defined.  Shouldn't have to do this since POSIX says <signal.h> is to be protected against multiple inclusion, but SUN defines signal stuff in both <signal.h> and <sys/signal.h> which confilct.  Furthermore they include <sys/signal.h> in <sys/param.h> so if you have <param.h> you cannot also include <signal.h>.
