Alpha is 64bit technology, it is still faster than any 32bit processor
(sometimes depending on application). SuSE sells it's Linux distribution
for Alpha processors with the Compaq C/C++ and Fortran compilers. They
are said to be among the best compilers available.

The Intel compilers are not compatible with certain GNU extensions
for C/C++, so the Linux kernel doesn't compile with it (afaik). If you
use ansi C/C++ the might be okay, they are avalabble for Itanium too, or
they will be soon. BTW Intel bought the Alpha processor design,
compiler technology from Compaq.
