Or even link to the so library which match the liballeg.a version.

When doing so, you should keep the to number X.Y. in soname, and .Z as
the minor number for compatible releases.

Yes. For this reason in WIPs the soname should contain all tree numbers,
x.y.z. So, for example, liballeg-4128.so would have the soname
"liballegro.4.1.28" (and symlinked to that name by ldconfig), and
liballeg-4130.so would have the soname "liballegro.4.1.30." But NOT
"liballegro-4.1", this would not allow ldconfig to see the difference,
the symlink would be called liballegro-4.1 pointing to the "latest"
version of 4.1.x (4.1.30 in this example), but the binary compatibility
is not guaranteed.

Exactly. This WIP would be frozen and only changed for bugfixes, no
major changes in the API/ABI.

Gruss/Regards,
