[Scons-users] Caching compiler side effects?

[Andrew C. Morrow]

Hi Bill -

Thanks for clarifying about side effect. In my particular use case, I
don't want the second generated file to be included among the objects
that will be linked. If I use a custom emitter that names this other
file along with the .o, won't Program and Library try in turn to pass
the file on to the link phase?

Thanks,
Andrew
