I'm usually not against using _VERSION_MAJOR.

What however I find disturbing and to be unnecessary churn, is this
systematic change to using it.

I would prefer that we only switch to using _VERSION_MAJOR when there is
a reason to do so (e.g. shared amongst many variables, like version, URL,
path URLs, etc...) while bumping a package or fixing it somehow, and
that we do not do that change on its own.

However, the name of the project is not OpenIPMI 2.0 Library. It's just
OpenIPMI. Upstream also has "OpenIPMI 1.3 Library" and "OpenIPMI 1.4
Library" download locations, each corresponding to the 'major version'
of the library.

Still, I agree with Arnout, and I don't think we should do those changes
just for the sake of adding _VERSION_MAJOR. It should provide an actual
improvement (but I can see that URL encoding above is a bit confusing to
read without the variable).

Yann E. MORIN.
