tup environment does not contain all env vars

[Mike Tavares]

When I check the environment (windows or mingw64 / git bash) while tup is running it does not contain all the environment vars.

I'm running 'env' and then running tup with a Tupfile that looks like this:

: test_set.bat |> env |> %B.mexw64

The resulting environments displayed are not the same. Many vars are missing from the tup run.

This is by design. See the manual at http://gittup.org/tup/manual.html, chapter TUPFILES, directive 'export VARIABLE' for an explenation.

Kind regards, Bernhard.
