Oh how I wish the solution was that simple.

The problem is that yacc(1) output is specific to the system on which
it runs: it can and does emit all kinds of environment-specific code.
Thus, the output of any one yacc(1) utility won't fit all environments.
This is why "utparse.c" was removed from the distribution.

The yacc(1) utility is required to be a part of any POSIX-conforming
development environment.  Have you considered informing the Cygwin
folks of this omission?
