I don't actually see this as a problem - that is, I don't see why any 
compile failure should be hard to fix for some system-specific reason.  
I'd rather just add such tests as normal tests, that break the build if 
they fail.

If .out is compiler output, I see no good reason for this to depend on 
run-built-tests; such tests should run unconditionally.
