Subject: bison weirdness with djgpp

I have been having some strange problems with the bison supplied with
djgpp.  I am porting an application I wrote on the Sun to the PC.  When
I use the %union construct in bison on the Sun (in conjunction with the 
-d flag when invoking bison) bison automatically puts a union declaration
for yylval in the .tab.c file, and includes an external declaration for 
it in the .tab.h file.  However, on the PC neither of these things happens.
Also, when I enable the inclusion of debugging code in the bison generated
file, I get additional undefined variable errors.  Is this port of bison
incomplete or broken?

Also, has gdb been ported for use with djgpp and demacs, or is this 
impossible under DOS?

Have many of the GNU utilities been ported to DOS via djgpp?

Thanks for any advice or assistance.
