[patch] enabling solaris sparc atomics

[Ian Holsman]

The solaris specific version of the atomics seems to work for me in 
limiting testing. I'll try it on several different types of sparcs
to make sure it's hunky-dory

what I need from the list:
        * non 2.8 machines
        * non GCC
I'll commit this on wednesday otherwise.
