[Scons-users] ParseDepends and duplicate with variant directories

Instead of improving the C scanner implementation, would a patch be accepted for a scanner that actually invokes the compiler with all the flags and then uses ParseDepends? It just seems "more correct" to use the compiler generated dependencies instead of parsing the file using a scanner like it's currently done. This way, the compiler can handle any crazy include combinations (even those that rely on compiler builtins such as #include_next). I know that this could be way slower than using a parser in Python.

Crazy organization in a third-party project whose source I can't change.
