dnl The following test is roughl taken from the cvs sources.
dnl
dnl If we can't find connect, try looking in -lsocket, -lnsl, and -linet.
dnl The Irix 5 libc.so has connect and gethostbyname, but Irix 5 also has
dnl libsocket.so which has a bad implementation of gethostbyname (it
dnl only looks in /etc/hosts), so we only look for -lsocket if we need
dnl it.
