SCons will build the file "test.h" for you, as you requested. But then 
its work is done. What you're doing with the file after it was built by 
SCons, is out of the scope. We track only changes in the sources of a 
target, not the target itself.

You either have to integrate the "change test.h" step into your actual 
build, if you really need it, or you should check in "test.h" to a VCS. 
Then you can restore it, if necessary.
Finally, another option is to simply remove the "test.h" file, and then 
run SCons again.

Hope this helps.

Best regards,

Dirk
