Is there even such option? There's /favor:AMD64, it is supposed
to be passed if you specify <instruction-set>opteron, and in any
case it only controls what processor the binary will be optimized to.
It does not control 64-bit code generation.

It is highly unlikely for this to return nothing if cl.exe in in PATH. Are you sure
that's the case?

Do you have a binary called

        "c:\\Program Files (x86)\\Microsoft Visual Studio 8\\VC\\BIN\\cl.exe"

Can you list all binaries called "cl.exe" in your VC\BIN directory?

How did you identify that?
