lib-ext isn't very well-conceived/constructed, IMNRHO! See 
https://github.com/dra27/opam/commit/f740058a639306c093de3b4f7425a01747239e97. 
Part of my reason for spending time last year implementing lib-pkg in the build 
system ...

I then hacked admin-scripts/compilers-to-packages.ml and changed the #directory 
entries to include src/{core,repository,format,tools} and src_ext and can run 
that script which I used to replicate the next branch on opam-repository and so 
rebased to create https://github.com/dra27/opam-repository/tree/next-windows 
(I've been doing a lot of work locally, which is why it's lagging behind master 
at the moment).

compilers-to-packages.ml will be a one-time thing, though, surely? Once OPAM 2 
goes live, surely the main repository will need to work in reverse, 
back-porting an OPAM 1.x.y repository?
