rrs 20dc61d3a4 Tons of fixes to get all the 64bit issues removed. 
This also moves two 16 bit int's to become 32 bit
values so we do not have to use atomic_add_16.
Most of the changes are %p, casts and other various
nasty's that were in the orignal code base. With this
commit my machine will now do a build universe.. however
I as yet have not tested on a 64bit machine .. it may not work :-(
