wrong behavior binary semaphore

[Arturo Perez Garcia]

Hello, thanks for the feedback. I checked the confdefs file and the 
macro CONFIGURE_MAXIMUM_SEMAPHORES is set to 0 by default. I don't know 
why I didn't get those errors.

Once RTEMS is correctly configured. Did you obtain the same results as 
me?

Thanks
