Comment:

 Thanks! You forgot to ifdef out the actual include but if I do that almost
 all interprocess tests pass on QNX 6.4.1.

 As a side note, there's a bug in the QNX kernel that I found when running
 the interprocess regression tests six months ago, that forces me to
 disable managed_mapped_file_test, managed_shared_memory_test and
 doc_managed_copy_on_write:[[BR]]
 ''If you create a shared memory object, mmap() it with MAP_SHARED, create
 a synchronization object (e.g. a mutex) in it, and then mmap() with
 MAP_PRIVATE to the same offset in the shared object, then the application
 and some some programs such as pidin and shutdown may hang. (Ref# 63369)''
