I'd go for the -S option (fixing mk-kinds-h.sh), as I don't like  
using stderr too much. But maybe the right way of doing it would be  
to create a file suffixed with .parse-tree (ie, create a.f90.parse- 
tree when compiling a.f90), similarly to what is done for dumping  
middle-end trees?

Thanks for taking care of this, Steven !
