Obsolete Constructs
*******************

   Autoconf changes, and throughout the years some constructs are
obsoleted.  Most of the changes involve the macros, but the tools
themselves, or even some concepts, are now considered obsolete.

   You may completely skip this chapter if you are new to Autoconf, its
intention is mainly to help maintainers updating their packages by
understanding how to move to more modern constructs.
