Invalid asms in libstdc++-v3/config/cpu/alpha/bits/atomicity.h

[Benjamin Kosnik]

great. Alexandre, can you post your patches to get it compiling? Or, if 
they are as discussed, can you check them in?

the type_info bits are as per the AIX discussion, and have to do with 
weak linkage most probably. 

thanks,
benjamin
