We have recently acquired an IBMRT on which we run AIX 2.2.1
I have tried to install GNU 18.52 using the m-ibmrt-aix.h and
s-usg5-2-2.h files. I ran into the following problems:

1. The optimiser pass of the C compiler crashed. Solution
   remove the -O option

2. The file hftctl.c was missing. Solution copy this file from
   /usr/lib/samples/hft

By doing this I was able to generate a temacs which ran in batch,
loaded the lisp files and dumped to a xemacs. However the xemacs
crashed when I try to run it. If I run temacs interactively it starts
up OK but then is completely dead i.e. it does not read any key
strokes at all.

I have tried using the older m-ibmrt.h files. This causes compilation
and link errors unless if undef HAVE_ALLOCA define C_ALLOCA and define
CANNOT_DUMP. The result when these are defined is no better, temacs
just crashes.

Before I delve deeper into the mysteries of all this I would like to
check that someone else has not already solved the problem. Are there
later versions of GNU emacs which do compile / work. I believe that
AIX 2.2.1 is recent version of AIX is the version of emacs I have not
compatible with this version?

All help and advice would be appreciated. If I do get thing working I
will of course post the answer to the net.
