I applied a matching patch for this:

https://cygwin.com/ml/cygwin-cvs/2015-q1/msg00079.html

Please give it a try.  If you're not set up to build your own Cygwin
DLL, I will generate a new developer snapshot soon, probably today or
tomorrow.

Btw., did you have a chance to test the pthread_join change from
https://cygwin.com/ml/cygwin/2015-02/msg00710.html in the meantime?


Thanks,
Corinna
