Here it is, /usr/include/signal.h. I've tried to force the cc compiler
but the result was the same (configure found gcc and used it by default).
The signals.h file in gcc's tree differs a bit. Mostly the __mips symbols
are changed to __mips__. Is it also important? If it is, tell me and I'll
send the diff. Thanks a lot.
Bye, Marek
