Ok, so how does one go about developing this sort of thing for Automake?  I'm 
certainly interested -- having time to do the work is always the issue, right?

I've found a number of tools which claim to do dependency tracking:

Foray http://code.google.com/p/foraytool/
Makedepf90 http://personal.inet.fi/private/erikedelmann/makedepf90
TCBuild http://macresearch.org/tcbuild-new-build-tool-fortran (precursor to 
foray?)
mkmf http://www.gfdl.noaa.gov/~vb/mkmf.html
fmkmf http://www.geos.ed.ac.uk/homes/hcp/fmkmf/

But what would be the best strategy for Automake?  I've seen discussion of this 
earlier:

In short, I'm asking for advice.  If I want the best chances of getting this 
feature (include as well as module dependency tracking in Fortran 77/90) into 
Automake, what's the suggested way to implement it?
