[Ur] cygwin, pthread_attr_init failed

[Adam Chlipala]

I've pushed a slightly different change to the public repo.  Your patch 
disables support for setting the stack size, but mine instead avoids 
making the fancier kind of call only when the user hasn't requested a 
custom stack size anyway.  It should still work in UNIX-land when 
someone does want to set the stack size.

Does my patch fix the problem?
