Ok, i see that now, ...

let's put them in a -dev package, what do you think ?

ideally, my c2caml tool should be able to regenerate them automatically ...

Yea, i am familiar with this, like transforming a enum into a list of flags ?

They are auto generated by the var2xxx stuff, isn't it ?

Ok, will do, could you tell me exactly what you need as .h, and i will but
then into the package.
