Is it OK to export it when defined? i.e.:

ifndef VERBOSE
   export VERBOSE = 1
endif

This is the local fix I'm using.

Replying to myself: No, most of them are also exported empty, but it is 
alright. Only VERBOSE will have a special meaning when defined empty.

The different kinds of verbose modes seem to be neither intuitive nor 
documented...


Thank you,
