[distcc] distcc always retries on localhost whether genuine error or not

[Philippe Mathieu]

Hello,

When running a compilation command with distcc, I would expect the compilation not to be retried locally when there is a "genuine" error on the remote distccd. However, anytime there is such a genuine error, the compilation is retried locally and then compilation errors shown. Only upon "accidental" errors would I expect the compilation to be retried locally to avoid an overall compilation failure. A sample output is provided below.

Am I doing (or expecting) something wrong? Is this a known issue?

Thank you very much for you time,

Philippe
