Unfortunately, the integration between Make and Guile is rather scant. Make exposes a couple of functions to Guile for evaluating a character string as a Makefile fragment (as if by the $(eval ...) function, I think) and for doing Make-style expansion of syntax, such as a $(variable) reference. With that, you can use Guile to generate Makefile material on the fly. Perhaps a variable assignment like "FOO := BAR" can be evaluated by Guile in order to create or modify a variable. I haven't seen an API into Make's rule base, whereby you could instruct it to update a target and such. I think, it should be possible for Guile code to generate a default target rule the fly, to throw it in Make's evaluation path, so to speak. I could be wrong on many points, but if it sparks more discussion, that would be good.
