+ * sim_client.c (main): Added better options parsing for more
+ flexibility in calling this program. Worked around
+ breakage in the Solaris Streams Sockets emulation where
+ getsockname() can not be used to find out the address of
+ a network interface.
+
+ * configure.in: If we are including both -lsocket and -lnsl,
+ #define BROKEN_STREAMS_SOCKETS.

* Makefile.in - Remove all explicit library handling and LDFLAGS.
