What strategy would you use when writing a library in Ada, that is to be called from e.g. a program written in C? In that case I think that using an initialization subprogram is the preferred method. If gprbuild is used to build the library, then a stand-alone library project can be used to ensure that the necessary elaboration code is called, but I have never used such a project type.
