Ah, I understand you.  And of course, if not in a shared library also.

(C++ programmers soon learn to avoid static initialization of objects in
namespace scope, except for the most trivial of uses, because the order
of initialization between translation units is unspecified.  I know gcc
makes priority specification available as a GNU extension for C++, but
that is only really useful in C++ if you don't link outside your own
code and stick to gcc, so lazy initialization is almost always better.)
