[Scons-dev] SCons cross-language support

[William Blevins]

Jason,

If I understand this correctly. I have a similar issue in Parts. I found

> rebuild as SCons thought the path changed.

This isn't (too my understanding) related to the patch in question.

All builders call a scanner or at least try to find a scanner to call
(whether implicitly or explicitly).  Sometimes this was simply handled as a
None case.  In order to finish the patch, I need to make a choice (Case A
or Case B).  Neither are 100% backwards compatible with previous behavior,
but both are reasonable I believe.

V/R,
William
