 Since 1.39, boost/interprocess/mapped_region.hpp depends on sys/shm.h
 (from POSIX XSI). The QNX 6 operating system doesn't have this header and
 thus Interprocess no longer works.

 boost/interprocess/shared_memory_object.hpp only conditionally includes
 sys/shm.h, like this:[[BR]]
 #if defined(BOOST_INTERPROCESS_SYSTEM_V_SHARED_MEMORY_OBJECTS)[[BR]]
 #  include <sys/shm.h>      //System V shared memory...[[BR]]
 #elif defined(BOOST_INTERPROCESS_POSIX_SHARED_MEMORY_OBJECTS)[[BR]]

 mapped_region.hpp uses a bunch of stuff from sys/shm.h though so the fix
 won't be quite that easy.

 Here are the rest of the errors from my NA-QNX641-qcc-gnu0x test
 runner:[[BR]]
 mapped_region.hpp:402: error: '::shmid_ds' has not been declared[[BR]]
 mapped_region.hpp:402: error: expected `;' before 'xsi_ds'[[BR]]
 mapped_region.hpp:403: error: '::shmctl' has not been declared[[BR]]
