I have been running emacs 18.55 under SunOS 4.0 and 4.03 on a Sun
4/110.  However, it is not possible to build emacs 18.54 or 18.55
under SunOS 4.1 on that workstation.

I build emacs by unpacking the distribution in /usr/local/dist-18.55
and mv-ing it to /usr/local/emacs.  /usr/local/emacs/src/config.h is
altered to #include s-sunos4.h and m-sparc.h.  I have changed no other
options in that file.

Issuing "make all" in /usr/local/emacs produces an executable, with
only one warning message:

	/usr/include/fcntl.h: 8: O_NDELAY redefined

when sysdep.c is compiled by make with the command:

	cc -g -Demacs -target sun4 -c sysdep.c

No error messages are generated.  xemacs is successfully dumped.
However, when I install emacs in /usr/local/bin/emacs, place
/usr/local/bin on my path, and run emacs without a file using the
command:

	emacs -q

I get the error message:

	Fatal error (6).Abort (core dumped)

I have removed:

	#define O_NDELAY FNDELAY

in /usr/local/emacs/src/s-sunos4.h and rebuilt using make all.  I get
the same results (a dump of xemacs that aborts as above when installed
and run).
