Are you building on a Core Duo (ie non-EMT64 capable) machine? If not, the
default code generation of the Apple system compiler should be to execute and
generate x86_64 code under 10.6. You can't take the output of 'gcc -v'
literally in 10.6. Apple builds fat binaries for their compiler and it only
reports the first set of specifications that it finds. So even when their gcc
executes and regenerates x86_64, the output of 'gcc -v' will report i386. I
opened a radar on that issue awhile back.
