#7184: atomic_cas32() uses Linux-only compiler intrinsic
------------------------------+---------------------------------------------
 Reporter:  jbaker@…          |       Owner:  igaztanaga  
     Type:  Bugs              |      Status:  new         
Milestone:  To Be Determined  |   Component:  interprocess
  Version:  Boost 1.51.0      |    Severity:  Problem     
 Keywords:                    |  
------------------------------+---------------------------------------------
 atomic_cas32() incorrectly assumes _sync_val_compare_and_swap() intrinsic
 is available on any host OS using GCC4.1+ when, as of GCC4.4, it is only
 available on Linux.  This renders it unportable.

 Problem was observed on QNX Neutrino 6.5.0.
