changes without updating version

[jcwright77]

It appears minor breaking changes have been made to the main branch without changing the version from 4.0.3 I grabbed this to rebuild and it was no longer compatible with metis 5.1.0. This issue is also in metis. It seems that the latest github checkins are compatible but neither is compatible with older copies of the same versions.

How about proper versioning?

Why not use tags, or better yet, releases, to track versions of this package? That would greatly help those of us who rely on it to build other libraries.
