Statically linking libraries is usually done for a different reason.
You can still distribute a custom version of a dynamically linked
library along with your application (and link to that instead of the
system-provided versions).

If there's an ABI-incompatible change in a library, it's done in a new
stable branch of the library, and is provided as another dynamic
library with the ABI version indicated in the filename. Pretty much
all systems (including Windows) provide multiple ABI versions of the
library available to link to (depending on which versions are still in
use). You can see those version numbers in the library names in

Not that any of that helps here, but it's still interesting.
