Yes, the Alpha is 64-bit, but there are a set of compiler flags that 
sort of "switch off" the top 32-bits of each word, and reduce the 
address space of the binary such that it must be loaded in the first 4Gb 
of virtual address space.

They were used to port a lot of VMS code that had all sorts of silly 
assumptions about various things being the same size, or being less than 
32-bits away.

As I said, I no longer have access to an Alpha, and can't find any of 
the Makefiles that I used with these flags, although "-taso" rings a 
vague bell.

Of course, they may have removed these flags since I used them, which 
was back when DEC was still DEC!

        Cheers,
