Hi Brian,

The result I get back is 16 which according to stderror is: "Mount device 
busy".
The mutex is being created within a running thread. It is very strange
that the same code compiles fine on other OS and that they don't give
back an error.

I'll try writing up a more simpler example that can be run,
also I'm compiling with -O3,I'm not sure how cygwin's modes
to gcc effect this level of optimization.
