This is correct. It isn't supported, and it is not likely to be supported in
the near future. It's a complicated issue, as there are no standards for
name mangling in C++, which makes linking to it dependent on the C compiler
version used to create the lib.

Write a small C wrapper which you then call from Pascal. This is what e.g.
Kylix does to access Qt.
