It is not a compiler dependent thing, it is a required part
of the language (if we are talking Ada = Ada 95)

Nothing tricky here, the method is portable and documented
clearly in the RM as a requirement for all implementations.

You can write your sources (both C and Ada) from the RM
requirements, but you will probably need to consult your
compiler documentation to see exactly how the binding and
linking is done, since this is, as always compiler and
OS dependent.

Paul's answers here would have been appropriate five years ago
for Ada 83, but are not appropriate for Ada 95 (of course if
you are still stuck using Ada 83, then the five years old
comments still apply to you :-)
