That isn't any different from Windows.

I mean, on Windows people have to explicitly specify if they want to
use static libraries, and I just don't see a convincing reason why
OS/2 should behave differently from everything else.
There is both the option of not installing shared libraries and
--enable-static, I am just not convinced the minor convenience
of a different default is worth extra code and making OS/2 behave
differently from everything else, including Windows.
