| Hi Akim,
| The reasoning was fairly tortured :)
| To document the patsubst internal change I had to invent a contrived

| There are two possible solutions:
| * document patsubst in the context of the user dep files patch, where
|   the behavour is truly static.
| * patsubst expand variables before they hit (enabled by
|   an option to protect people (e.g. myself) who already abuse Automake
|   by passing through patsubst expressions).
| From your reaction, I suspect the second might be the better
| solution. Unfortunately it is more work...

Yep, by default Automake must not let the users do nonportable
things.  I'm sorry about that, but I believe it's a strong

I'd like to hear from Alexandre and Tom though.
