>> as I see sys/wait.h define this macro. So it's include should be enough. But why it doesn't want to link (LINK but not to compile!) i don't know yet. I will try to solve it myself but if anyone has ideas - you are welcome.
FIX:
make clean
autoconf
./configure
Bingo. SARG maintainers seemed to have forgotten this step before tarballing.
