?X: This order is chosen so that libraries  -lndir, -ldir, -lucb, -lbsd,

?X: libraries, and may not be as reliable as the standard c library.
?X: The ordering of c_s, posix, and cposix is a guess and almost
?X: certainly wrong on about half of all systems.

Some versions of Unix support shared libraries, which make executables smaller
but make load time slightly longer.

On some systems, mostly newer Unix System V's, the shared library is included
by putting the option "-lc_s" as the last thing on the cc command line when
linking.  Other systems use shared libraries by default.  There may be other
libraries needed to compile $package on your machine as well.  If your system
needs the "-lc_s" option, include it here.  Include any other special libraries
here as well.  Say "none" for none.
