Currently ppx extensions and Camlp4 cannot coexist:
https://github.com/ocaml/camlp4/issues/55
So I'm trying to create something similar to
IFDEF SOMETHING THEN
val v1 = ...
val v2 = ...
...
END
But looks like it's impossible to define a extension which would
(conditionally) include signature items. Is it really so?

But probably, ppx extensions can coexist with cppo:

Yes it does, thank you. Unfortunately any preprocessor is not
compatible with ocamlmerlin so I tried to get rid of them completely;
the only hope is that merlin people will implement cppo support some
day.
