Hi Laura,

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
