Remove volatile qualifiers, and regarding to memory barriers, the Novell developer
kit documentation "NDK: Libraries for C (LibC), Volume 2; Section I, General C
Services; Atomic Functions", says:

"An atomic function is guaranteed to complete its memory operation before any
other processor or bus agent can access the same memory."

So I presume that the atomic functions issues memory barriers.
