I've checked in a change that moves the entry into the Installation
Changes section and makes it (IMO) slightly clearer:

  ** Deprecated machine types and operating systems
  
  Certain machine types and operating systems have been deprecated.  On
  these systems, configure will print a warning and exit, and you must
  edit the configure script for compilation to proceed.  The deprecated
  systems will not be supported at all in Emacs 23.  We are not aware of
  anyone running Emacs on these systems; if you are, please email
  address@hidden to take it off the list of deprecated systems.
  
  *** Deprecated machine types
  pmax, hp9000s300, ibm370aix, ncr386, ews4800, mips-siemens, powerpcle,
  and tandem-s2
  
  *** Deprecated operating systems
  bsd386, bsdos2-1, bsdos2, bsdos3, bsdos4, bsd4-1, bsd4-2, bsd4-3,
  usg5-0, usg5-2-2, usg5-2, usg5-3, ultrix4-3, 386bsd, hpux, hpux8,
  hpux9, hpux9shr, hpux10, hpux10-20, aix3-1, aix3-2-5, aix3-2, aix4-1,
  nextstep, ux4800, uxpds, and uxpv

As for changing the configure script to add an option to enable
deprecated builds, it would be fine if someone wants to do it, but I
don't think it's necesary.  I *seriously* doubt anyone's using Emacs
22 on these systems, and anyone who is surely has the expertise to
make the required simple change to the configure script.
