ZeusCmd.exe not returing exit code on error?

[pmcevoy]

Hi there,
I'm generating code using ZeusCmd.exe as part of an automated build procedure. I'm using the MSBuild \"Exec\" task, and I want the build to fail if code fails to generate, however this does not seem to happen as ZeusCmd.exe does not seem to return a non-zero exit code on error.. Is this correct?
