Why not? Is there something non-deterministic in the compilation

Ideally, version x of gcc should produce the same output natively
as when cross-compiling.

Or have I missed something important?

(I'm actually quite fond of the idea of dist-cc sending pre-processed
C code to remote (faster) machines and getting unlinked object code
back. I haven't got a good use for it yet, but the _idea_ is neat.)
