flock() system call is detected as non-working on AIX by configure.
Specially strange that I've failed to find something useful in the net 
re this.
Alternative (USE_FCNTL) ifdef is definitely less tested.
I will check in on linux and reply after it.

There was an old issue with some flags in mmap() non working on AIX. But 
we do not use that flags. Therefore mmap() was artificially turned on in 
common.h. As long as currently it seems to work from configure POV your 
change is absolutely correct.
