If an environment variable > is set, that value gets added as a .comment section to the necessary binaries. This is not really my purview but ... can I just say that I really do not like using environment variables to control build behaviour. It makes reproducing a build much harder. Especially when you are trying to reproduce a bug report from a user who does not even know that the environment variable exits. Cheers Nick
