I just brought up 18.55 on my 302 running 5.3.2.  It took a bit of work,
but proof by existence is the best proof.

First, you cannot use any libraries which are shared.  On my system, this
includes libX11_s.a.  (The _s suffix is the convention for shared library
names.)

I found that I could not compile fns.c with the -O flag.  I don't know why,
but when I did, Emacs died in concat() with Error 11 whenever it tried to
access things from the DOC file.  (It appeared to read in the file without
problems, but died looking up the string.)  When compiled without the -O
flag, everything is fine.

I used the distributed m-intel386.h.  I modified s-usg5-3.h to define
HAVE_PTYS, SYSV_PTYS, and HAVE_SOCKETS.  I also had to add:

	#define LIBS_MACHINE -lsocket

(I have Lachman TCP installed.  This should also work with Wollongong
(sp?), but I haven't tested that.)

I also had to modify a few files in the src directory.  In particular, my
system doesn't have <sys/pty.h> (needed in process.c when SYSV_PTYS is
defined).  I included <sys/stream.h> and <sys/ptms.h> instead and
everything works.

As I mentioned, I could not include X11 support.  Dumping shared libraries
is unsupported.  Somebody once sent me patches to dump with shared
libraries (or was it SunOS' dynamic libs), but I lost it.

I also made the following chages to sysdep.c.  As before, since there is no
standard for include files and packages like TCP, you may or may not need
all of these patches.

The second patch is needed because my system does not have <sys/sioctl.>
(The comment right above the include file mentions the problem.)

The other patches are to get termio working.  I had to include some extra
files and my version of SysV calls the struct tc, not tchars.

Enjoy,
