No. O_NOCTTY was internally fixed by not using it on Cygwin :-)

There were three groups of tests that were using pty, each run in a 
separate zsh invocation (Y01completion.ztst, Y02compmatch.ztst, 
Y03arguments.ztst). When run from within make in `make check', second 
and third group failed with obvious reason that nothing was read from 
master side of pty. If I run each one separately, everything worked. 
Additional problem was, that cleanup of failed test failed as well - 
there remained hung zsh attached to pty slave in state `I' (as reported 
by ps).

It may be possible that some change in zsh fixed it but I do not 
remember anything directly related.
