For applications loaded as a set of "modules", the crtstuff objects
- linked in (crtbegin/end) are tailored to provide this service a-la C++
- constructor fashion, typically triggered by the VxWorks loader. This is
- achieved by way of a special variable declaration in the crt object, the

- step documented for C++. The de-registration is handled symmetrically,
- a-la C++ destructor fashion and typically triggered by the dynamic

- common datastructure, libgcc should be one of the modules (vs being
- partially linked against all the others at build time) and shall be

For applications linked with the kernel, the scheme above would lead to
- duplicated symbols because the VxWorks kernel build "munches" by default.
- To prevent those conflicts, we link against crtbegin/endS objects that
- don't include the special variable and directly call the appropriate
- function here. We'll never unload that, so there is no de-registration to
- worry about.

For whole applications loaded as a single module, we may use one scheme
or the other, except for the mixed Ada/C++ case in which the first scheme
would fail for the same reason as in the linked-with-kernel situation.
- We can differentiate by looking at the __module_has_ctors value provided
- by each class of crt objects. As of today, selecting the crt set with the
- ctors/dtors capabilities (first scheme above) is triggered by adding
- "-dynamic" to the gcc *link* command line options. Selecting the other
- set of crt objects is achieved by "-static" instead.

This is a first approach, tightly synchronized with a number of GCC
configuration and crtstuff changes. We need to ensure that those changes
