That is not a -I flag, though. If you try -I I think you will get a failure. Looking a bit closer it is because the dependency stuff uses CPPFLAGS which doesn't support per file/dir flags.
OK, if it's the dependency step, that's a different story. untested patch:

Thanks - have been playing with this a bit. The problem is that rules.mk goes through the files in the directory one by one in a shell 'for' loop, so $(@F) isn't relevant. I am wondering in fact where I need to replace the dependency file generation with something which creates separate .deps for each file, and then concats them in a separate rule.
