List of all includes (dependencies)

[thundertaker]

Hello,
is there is a way to generate list of files GPP will include?
I would like to generate dependencies list for Make,
as described here:

If you do add arguments to enable such a function, you'll have to use different ones from the C pre-processor, as the '-M' argument is already in use by GPP to do something else.

Perhaps a long-form argument, like '--makefile-spec', could be used; one could also add versions like '--makefile-spec-file' or '--makefile-spec-nosys'.
