  #	Various manipulations on the search path used at runtime to
  #	find shared libraries:
  #	1. If the X library binaries are in a non-standard directory,
  #	   add the X library location into that search path.
  #	2. On systems such as AIX and Ultrix that use "-L" as the
  #	   search path option, colons cannot be used to separate
  #	   directories from each other. Change colons to " -L".
  #	3. Create two sets of search flags, one for use in cc lines
  #	   and the other for when the linker is invoked directly.  In
  #	   the second case, '-Wl,' must be stripped off and commas must
  #	   be replaced by spaces.

  #	Check for the existence of various libraries.  The order here
  #	is important, so that then end up in the right order in the
  #	command line generated by make.  The -lsocket and -lnsl libraries
  #	require a couple of special tricks:
  #	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.
