I realize that having an additional step can be a pain, but there's
additional information that we intend to add to the provider  
definition file
that the -G option lets us do. That said, we some investigation into  
adding
an option to the linker so while we're not going to get rid of the .d  
file,
we may make it possible to pass in the appropriate .d file to the final
linker invocation. This solves a few problems including IPO and  
dealing with
archives (.a libraries).
