Hello, There has been some confusion about detecting BSD style signals versus SYSV style. I have updated the configure script to be less fascist about BSD and hopefully this fixes the problems. Get it from: ftp://agnes.dida.physik.uni-essen.de/home/janjaap/updates/ Now, hopefully, FreeBSD is considered BSD again (Peter?) I think SunOS and Solaris are BSD variants too, right? If this still doesn't work, I would like to see your <signal.h> and <sys/signal.h> header files. The problem is that some SYSV systems #define these BSD signals but don't support them unless you link -lbsd, so I made BSD detection more strict (so strict in fact that FreeBSD was no longer considered BSD ;-) Hope this helps, JanJaap --- The latest & greatest in software, hardware and manswear.
