A question for you DECie techie types from a total outsider.  Does the
new Alpha architecture have native 64 bit integers?  How are they
organized?  As a natural extension of DEC's little endian 32 bit
integers?  Or something else?

Will Alpha C compilers have 16 bit shorts, 32 bit ints, and 64 bit
longs?  Will FORTRAN have INTEGER*8?

Do the new MIPS chips have 64 bit integers, and are they the same as
DEC's?  Do they have them in both big and little endian flavors, as
they do with 32 bit integers?  How about HP (PA) and IBM (POWER)
architectures, which I understand are also at least potentially 64
bit.  It seems to me that with 64 bits to play around in there is even
more potential for incompatabilities and big/little endian type warfare
than with 32 bits, so I hope somebody is thinking about this.
