Hmmm.  Thought the "w" referred to the W bit in the PSW being set to 1.
Setting this bit does change the code architecture, although OS support
is obviously needed as well.

I believe that this was taken into consideration in the config.guess
patch that I circulated.  For these machines, the code level will be
2.0 or 2.0n (no "w") and hppa64 will never be set.

The HP compiler has separate options to set the architecture and data
model, although they are far from independent.
