[zeromq-dev] platform checks.

[Martin Sustrik]

George,

Related issue (ZMQ-104) is solved. POSIX semaphores are made default 
with specific optimisations for Linux, OS X and Windows platform.

Together with ZMQ-103 (don't use MSG_DONTWAIT) this should solve your 
problems when porting to AIX and HP-UX. Let us know whether everything 
builds OK now.

Thanks.
Martin
