found it.
couple of transcription errors in the old macros only. new inrtinsic code
worked fine.
all shifts require a 64bit shift arg so made them regs again to minimize mem
accesses.
also dont need the -fPIC options. so I removed them too. static lib after
all.
patch attached.
apologies for the dep issue. I saw it in the log. didnt update due to my
debug session on this.
also the "new" intrisics are much slower. I had a look at the assembly
produced and its quite inefficient at optimising the registers (gcc3.3.4).
Id keep the older macros for now for performance reasons.

cheers
mark
