- # This creates a compressed (14 bits) tar file that can be copied to a DOS
- # machine, unpacked and compiled with Borland C++ 2.0.
-
- # This is for groff version 1.04. It will probably need work for
- # other versions.
-
- # The grammar is yacced here, because I don't have a yacc on my DOS
- # machine. The resulting .tab.c file is split up; I found the
- # compiler ran out of memory otherwise. The sed command that does the
- # splitting assumes you're using the SunOS 4.1.1 yacc.
- # (Bison-generated parsers need alloca() which Borland C++ does not
- # have.) You'll need to tweak it for other yaccs: in particular you'll
- # need to change the `tabs' variable, so that it matches the names of
- # the external arrays of ints generated by your version yacc: it is
- # these that are split off into another file. You may also need to
- # change tabtype to `short' if the tables are arrays of shorts.
