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

 445   #     Check for the existence of various libraries.  The order here

 447   #     command line generated by make.  The -lsocket and -lnsl libraries
 448   #     require a couple of special tricks:
 449   #     1. Use "connect" and "accept" to check for -lsocket, and
 450   #        "gethostbyname" to check for -lnsl.
 451   #     2. Use each function name only once:  can't redo a check because
 452   #        autoconf caches the results of the last check and won't redo it.
 453   #     3. Use -lnsl and -lsocket only if they supply procedures that
 454   #        aren't already present in the normal libraries.  This is because
 455   #        IRIX 5.2 has libraries, but they aren't needed and they're
 456   #        bogus:  they goof up name resolution if used.
 457   #     4. On some SVR4 systems, can't use -lsocket without -lnsl too.
 458   #        To get around this problem, check for both libraries together
