+Groff has been compiled on a Sun 4 under SunOS 4.0.3 with g++ 1.37.1
+and with AT&T C++ 2.0, and on a 386 PC under 386/ix 2.0.1 with g++
+1.37.1 using Michael Bloom's GNU COFF patches. You may encounter
+problems on other machines that I cannot anticipate.
+
+If you are using g++, you will need to install the header files from
+libg++. The only other parts of libg++ used by groff are contained in
+the files xyzzy.c and gnulib3.c; the libg++.a that I use contains only
+xyzzy.o and gnulib3.o. You don't need xyzzy.o unless you're using GNU
+ld.
+
+If you are using g++ 1.37.2 alpha, you'll need the following fix (from
+Michael Tiemann):

+
+On a Sequent Symmetry S27 running Dynix 3.0.17, you'll need to use GNU
+make or add 'MAKE=make' to Makefiles which use $(MAKE). You'll also
+need to change
+
+ dev=${GROFF_TYPESETTER:-@DEVICE@}
+
+to
+
+ dev=$GROFF_TYPESETTER
+
+in groff.sh. You should use gcc to compile xditview.
+
+You should only have to edit the top-level Makefile. The comments
+should make it clear what has to be changed. If you don't have a
+separate directory tree for local manual pages you can make
+MAN[157]EXT be l (that's an ell) or n, and MANROOT be /usr/man. The
+changes you make to the top-level Makefile will be propagated to
+sub-makes, but this won't happen if you invoke make in the
+sub-directories.
+
+You might also need to edit groff.sh. This is a shell-script that
+runs gtroff, an appropriate postprocessor and optionally various
+preprocessors. (Actually, the shell-script is created from groff.sh
+by substituting for some variables surrounded by @s). If your kernel
+doesn't understand #!, you will need to arrange for the script to be
+run by /bin/sh in some other way.
+
+If you want to use existing troff drivers you should change groff.sh
+so that it recognises them. It is also a good idea to copy over the
+dev* directory for the device into a directory that's only searched by
+groff (eg /usr/local/lib/groff/font), so that you can take advantage
+of the groff extensions to the DESC and font formats. Groff only uses
+the ASCII versions of the device files so you only need copy them. If
+you want to use GNU eqn, it is essential that the font files contain
+correct height and depth information. The format for this information
+is described in the groff_font(5) page. The best way to add this
+information is to modify the program that generates the font files.
+As a last resort you could try using the program addftinfo: it
+attempts to guess plausible heights and depths. To obtain good
+results you would probably have to do more work on addftinfo.
+
+To compile everything, just do a `make'. If that works, then do a
+`make install'.
+
+If you have problems compiling pic/pic.tab.c or eqn/eqn.tab.c, you might
+want to try using your system's yacc. Set YACC=yacc in the top-level
+Makefile, and also do
+
+ mv pic/pic.tab.c pic/pic.tab.c.dist
+ mv eqn/eqn.tab.c eqn/eqn.tab.c.dist
+
+so that the parsers will be regenerated using yacc (the supplied
+*.tab.[ch] files were generated by bison.)
+
+If you want to install xditview, you'll need to do that separately:
+change directory to xditview, edit the Makefile, do a make and a make
+install. You'll need to be running X11R4.
+
+The dvi files produced by grodvi can use fonts at non-standard
+magnifications. You may need to compile fonts with Metafont at these
+magnifications. The CompileFonts script in the dvi/devdvi directory
+may help you to do this. (It will take a *long* time.)
+
+If you have problems printing existing troff documents, read the
+section on `Incompatbilities' in gtroff(1). If you have existing
+macro packages that are in the habit of omitting the space between a
+macro or request and its arguments, it is good idea to produce a
+version with spaces so that you can use it with groff (without having
+to use the -C flag). The file macros/fixmacros.sed is a sed script
+which will attempt to edit a file of macros so that it can be used
+with groff without the -C flag. If you have the DWB 2.0 mm macros
+installed on your machine, you might want to do a `make install.mm';
+this will copy the mm macros to groff's macro directory and fix a few
+problems that occur when using the mm macros with groff; this requires
+the `patch' program. If the patch in macros/mm.diff is rejected,
+carefully apply it by hand.
+
+You can share groff with a friend who has the same type of machine as
+you, but does not have a C++ compiler. First do `make bindist'; this
+will create a subdirectory `bindist' containing a set of binaries, a
+Makefile and a README. If you want to strip the binaries, now do a
+`make strip' in the bindist directory. Rename the bindist directory
+to something more meaningful, tar it up, and give to your friend along
+with the original groff source distribution. Your friend can then
+install groff just by editing the Makefile in the bindist directory
+and doing a make there; this will automatically install the non-binary
+parts of the groff source distribution as well as the binaries from
+the bindist directory.
