1. setsockopt in rmt.c needs cast to avoid prototype conflict

2. rmt needs to be linked with -lsocket and -lnsl.  I've added explicit
   tests for /lib/libsocket.a and /lib/libnsl.a in autoconf.in...  This
   may not be the way you want to do it.

3. Makefile.in changed to add $(LIBS) to link of rmt. see #2 above

4. None of the contortions to find out the page size in getpagesize.h
   worked.  If _SC_PAGESIZE is defined, use sysconf(_SC_PAGESIZE).
