Bison 1.32 wordlessly crashes on startup with the following trace; this
is with DOS 5.0, stock djdev 2.03, and either bash 2.04 or command.com.
The very same .y file compiles without problems using bison 1.30.  It also
compiles okay with bison 1.28, although in this case some of the `#line'
directives written to y_tab.c are incomplete (can be fixed by hand).
If it helps, I also found that bison 1.30 will work fine with the
bison.hairy and bison.simple supplied with bison 1.32.

% bison --version
