 (** This file is a hack that lets us use Psatz without importing all sorts of axioms about real numbers. It has been created by copying the file Psatz.v from the Coq distribution, removing everything defined after the lia tactic, and removing the two lines importing RMicromega and Rdefinitions.

When compiling I get:

``````*** Warning: in file prelude/psatz_axiomfree.v, declared ML module micromega_plugin has not been found!
*** Warning: in file prelude/psatz_axiomfree.v, declared ML module micromega_plugin has not been found!``````

Anything we can do about that?

Add a "grep" to the Makefile to filter it? ;)

I have no idea what this warning is trying to tell me -- after all, it is loading the module. If I use a bogus name, I get that error and also, later, a failure to find the plugin in the load path. On the plus side, the warning only appears when compiling `psatz_axiomfree`, which will not usually be recompiled. ;)

I also wonder about the intended behavior of adding a `Declare ML Module` that refers to an ML module in another Coq project. In this case it seems to work, but is that something we can rely on? Maybe we should create a Coq bug report about this error message and see what they have to say.

shrug I don't care strongly, this is a hack anyway, and if it stops working, then whatever. But I won't stop you. ;)
