Subject:   -60- Why does GNU Emacs not compile, or compile but not run?
Date: 08 Oct 1994 00:00:01 EST

  You probably have an old version.

  Emacs 18.59 is the last release of Emacs version 18. It builds and
  runs correctly under IRIX 4.0.x. Some earlier versions failed to
  compile (because cc now needs -cckr for K&R C compatibility) or
  failed to run when stripped (because of object file format changes).
  For the latter reason, the file unexmips.c in some versions of Epoch
  and Lucid Emacs should be replaced with the same-named file from the
  GNU Emacs 18.59 distribution.

  Karsten Kuenne <kuenne@desy.de> has patched Emacs 18.59 to work with
  IRIX 5.0's new object file format. The patches are at
  ftp://ftp.desy.de/pub/gnu/emacs/emacs-irix5.0-patches.

  Emacs 19.28 is the most recent release of Emacs version 19 at this
  writing; it builds and runs correctly under IRIX 4.0.x and 5.x with
  recent compilers (IDO 4.1.1 or newer). Be sure to read about Iris
  quirks in etc/MACHINES.
