I've had the same problem building Cygwin setup with bison-1.875.
Looking at the ChangeLog between 1.875 and 1.875a
(<http://savannah.gnu.org/cgi-bin/viewcvs/bison/bison/ChangeLog.diff?r1=1.976&r2=1.990>)
it does seem that using 1.875a will not exhibit this particular problem.
It doesn't look like another stable release will happen anytime soon...
Can the [curr] bison package be "upgraded" to 1.875a (leaving [prev] at
1.75) at some point?
