The above looks good: both bison(1) and flex(1) were used to generate a
Cygwin-specific parser and scanner, respectively.

Hmm...  There could be something wrong with the file "c0.cdl".  Would
you please send it to me.

If there's nothing wrong with the file "c0.cdl", then we'll need to
discover the cause of the syntax error.  This will require putting
the bison(1)-generated parser into a debugging mode.  If the Cygwin
bison is like our Linux bison(1), then the makefile rule for the target
"ncgentab.c must be modified to add the option "--debug" to the bison(1)
invocation.  Then the file "ncgentab.c" must be removed and the commands
"make all" and "make test" re-exeucted.

There might be something else that's necessary in order to obtain
debugging information from the parser.  You'd better check with the
man(1)ual page for bison(1).

The makefile looked OK.

No problem.
