No, it means that _POSIX_THREADS  is not defined. 

For the pthread support of Cygwin you can look at Cygwin's pthread.h
(which basically says that this is implemented:
http://www.opengroup.org/onlinepubs/7908799/xsh/pthread.h.html ) or at
the Cygwin API docs at http://cygwin.com/cygwin-api/std-posix.html#AEN85
(which seems a little sparse).
