      PKG_CONFIG_VARS.<lib>
      and PKG_CONFIG.var.<lib>.<var>.
    - becomes internal include file and therefore
      renamed to mkc_imp.pkg-config.mk.  Symlink mkc.pkg-config.mk is
      provided for backward compatibility.  mkc_imp.pkg-config.mk is
      included by mkc.prog.mk and mkc.lib.mk.

  mkc.intexts.mk:
    - becomes internal include file and therefore
      renamed to mkc_imp.intexts.mk.
      Symlink mkc.intexts.mk is provided for backward compatibility.
      It is included from mkc.prog.mk, mkc.lib.mk and mkc.files.mk.
    - New variable INTEXTS_REPLS. See mk-configure(7).

  mkc.lib.mk:
    - includes mkc_imp.intexts.mk
    - supports SCRIPTS* variables (includes newly created
    mkc_imp.scripts.mk)
    - New variable MKDLL for creating dinamically loaded libraries
    (<lib>.so).

  document their own variables.  Further improvements of man page are
  needed.

equal.
  The same for "yes", "Yes"...
