Subject: [PATCH] configure.ac: --without-versioned-path option introduced

  Using this option will result in Ghostscript being installed into a
  paths which do not contain its version in them, which can be useful
  on some distributions.

  As a result of using this option, the Ghostscript's search path will
  be updated as well, to include correct files locations.

  This option is disabled by default, and configure's help page states
  that using this option is dangerous, risky and unsupported.
