Hum, sorry for my very confusing previous answer. I thought "Camlp4Bin
*after* minimal". But you've tried that.

After thinking a little more, I can explain what's happening there is
two modes to get into Camlp4 pipeline. The first one is through
registration and the second one is through dyn-linking of cmo files on
the command line.

Here your Minimal module is neither on the command line nor registered.

To register it make a functor around your grammar extension and call
Camlp4.Register.OCamlSyntaxExtension.
