The RES builder that gets populated by the 'mingw' tool uses SourceFileScanner to scan for dependencies, but it should use SCons.Scanner.RC.RCScan for the scanner, like the builder populated by the 'msvc' tool does. By using the wrong scanner, it fails to capture dependencies for things like ICON and BITMAP external resource, which the RCScan does.

The fix should be very simple: on line 125 of Tools/minw.py, simply change "SCons.Tool.SourceFileScanner" to "SCons.Scanner.RC.RCScan()". I've tested that it works at least, but I'm not sure if there are other side effects that need to be tested.
