I don't know if it is the case for this specific header, but I always try to
make the initialization explicit. This mainly because then in case of
changed library names the user can simply override by passing the new name
to the initialization routine.

Note that there is a difference in an own header (that is usually part of
the project), and a header that is mainly used precompiled. The latter has
to last longer.
