I don't think so.  Since all 64 bit offerings to date have made
the right choice (commonly referred to as LP64) where longs and pointers
are 64 bits but integer stay at 32 bits, most of the 64 bit porting
[ for applications that need it ] has been done.

I think most people will go directly to stage 2.

Though I think HAL has made a different choice for it's 64 bitversion of
Solaris, making both ints and longs 64 bits.
