Define MS functions analogous to ns_etc_directory, ns_exec_path, and
ns_load_path. For simplicity/consistency, we can rename these to
something like "platform_etc_directory" etc (or reloc_, or whatever_),
then NS and MS Windows can use the same function names. Then we can just
replace the #ifdef HAVE_NS in callproc.c with #if defined HAVS_NS ||
defined WINDOWSNT.
