ocamlmake problem

Hi all,
I'm trying to use ocmalmake + camlp4 to re-use the same
code with dynlink in byte-code or without dynlink in native 
code. Do to this I'm using pa_macro to remove dynlink part of
the code. Now I'm trying to glue everything together with ocamlmake.

Attached there is a small example. Basically the problem is that if
I use the SUBPROJS pragma, the PRE_TARGETS are ignored. How can I 
do this ?

:)
