I looked somewhat further and found out the curious fact that on MacOSX 10.5.x both /usr/include/signal.h and /usr/include/sys/signal.h exist!
That is normal, signals have a portable interface, as defined in ISO C99. That is the interface provided in /usr/include/signal.h. It is also possible to have a system-dependant interface, and that is in /usr/include/sys/signal.h. On linux, this is a stub that simply includes /usr/include/signal.h. So the question is: does /usr/include/sys/signal.h include something important on Mac OS X 10.5 that it didn't in previous versions, or is something else changed? The only macbook I have runs 10.2, so I have no way of testing any of this myself. Best wishes, Taco
