"Well ..."
I'd rather not make this transition without a bit more discussion.
[I would prefer to avoid automake.]

One question and one observation:

Question: can automake handle dependencies on machine generated files?
I think(!) the answer is "no", so automake doesn't solve all problems.

Observation: gdb no longer manually describes dependencies (*1) yet it
doesn't use automake.

(*1): I realize it's more complicated than that, e.g. source files from subdirs.
