I think that any reasonable log library must be compiled to it's own lib due
to the intermodule singleton requirement. If some developers here think it's
not an important feature or that programmers are better off without separate
modules, please consider that users of your generic libraries may not be in
the more trivial scenario with only one statically built .exe.
