I've compiled emacs 19.27 on an aviion running dgux 5.4.2, in the elf
environment.  (Too bad it can't be compiled in the bcs environment,
since then the binary could be run on other m88k machines, but I'm not
willing to put in the work myself, so I'm not complaining too hard ...)

I configured it as m88k-dgux5.4.2 (which used s/dgux5-4r2.h).  Compiling
with GCC 2.5.8.

I had to define three things in src/s/dgux.h.  Otherwise, the
compilations of the replacement functions in sysdep.c failed
miserably. Hmm, I see configure was supposed to check for these, so this
bug report is next to useless, I need to find out why configure failed
to define them.  Sorry.
