Looks like an excellent suggestion, I didn't think of that. Thanks!

Anyway, if someone else knows the answer to the libtool question, I'd be
happy, if only for learning purposes :)

That's exactly what I wanted to know. But it strikes me that from
libtool 1.x to 2.x there's no ABI change. Is this correct?

I don't know exactly what libtool does (I'm not a C programmer -well,
apart from very basic stuff), but in general major version updates break
compatibility, therefore my concern.
