    #	Check for the existence of the -lsocket and -lnsl libraries.
    #	The order here is important, so that they end up in the right
    #	order in the command line generated by make.  Here are some
    #	special considerations:
    #	1. Use "connect" and "accept" to check for -lsocket, and
    #	   "gethostbyname" to check for -lnsl.
    #	2. Use each function name only once:  can't redo a check because
    #	   autoconf caches the results of the last check and won't redo it.
    #	3. Use -lnsl and -lsocket only if they supply procedures that
    #	   aren't already present in the normal libraries.  This is because
    #	   IRIX 5.2 has libraries, but they aren't needed and they're
    #	   bogus:  they goof up name resolution if used.
    #	4. On some SVR4 systems, can't use -lsocket without -lnsl too.
    #	   To get around this problem, check for both libraries together
    #	   if -lsocket doesn't work by itself.

#	The code below deals with several issues related to gettimeofday:
#	1. Some systems don't provide a gettimeofday function at all
#	   (set NO_GETTOD if this is the case).
#	2. SGI systems don't use the BSD form of the gettimeofday function,
#	   but they have a BSDgettimeofday function that can be used instead.
#	3. See if gettimeofday is declared in the <sys/time.h> header file.
#	   if not, set the GETTOD_NOT_DECLARED flag so that tclPort.h can
#	   declare it.

# the --cache-file=FILE option to use a different cache file; that is
# what configure does when it calls configure scripts in
# subdirectories, so they share the cache.
# Giving --cache-file=/dev/null disables caching, for debugging configure.
# config.status only pays attention to the cache file if you give it the
# --recheck option to rerun configure.
