 Creating Configuration Links
 ============================
 
    You may find it convenient to create links whose destinations depend
 upon results of tests.  One can use `AC_CONFIG_COMMANDS' but the
 creation of relative symbolic links can be delicate when the package is
 built in a directory different from the source directory.
 
  - Macro: AC_CONFIG_LINKS (DEST:SOURCE..., [CMDS], [INIT-CMDS])
      Make `AC_OUTPUT' link each of the existing files SOURCE to the
      corresponding link name DEST.  Makes a symbolic link if possible,
      otherwise a hard link if possible, otherwise a copy.  The DEST and
      SOURCE names should be relative to the top level source or build
      directory.  This macro is one of the instantiating macros; see
       Configuration Actions.
 
      For example, this call:
 
           AC_CONFIG_LINKS(host.h:config/$machine.h
                           object.h:config/$obj_format.h)
 
      creates in the current directory `host.h' as a link to
      `SRCDIR/config/$machine.h', and `object.h' as a link to
      `SRCDIR/config/$obj_format.h'.
 
      The tempting value `.' for DEST is invalid: it makes it impossible
      for `config.status' to guess the links to establish.
 
      One can then run:
           ./config.status host.h object.h
 
      to create the links.
