+dnl set OS libraries specific to an OS:
+dnl libnsl/libsocket are needed only on solaris and some svr4 systems.
+dnl Using a typical macro has proven unsuccesful, because on some other
+dnl systems such as irix, including libnsl and or libsocket actually breaks
+dnl lots of code. So I am forced to use a special purpose macro that sets
+dnl the libraries based on the OS. Sigh. -Erez.
