[Scons-users] env.Command and _process_ environment variables :-(

[Pedro Larroy]

Hi

I reproduced with a minimal setup. I think it's a bug, see the
attached zip file. When executing run.bat  the two environments
differ, the one that is displayed by show.py lacks VS11 related stuff
in the PATH.

Should I fill a ticket?

Pedro.
