BPL : problems with constructors?

From: Lorien Dunn (l.dunn_at_[hidden])

Hullo,

        I'm getting some errors I cant make sense of. They are happening in a set of
inter-object Midi reception and transmission classes. These are the only
classes affected out of about 75. Attached is a file containing the class
interfaces concerned, and the compiler errors.

        I'm using Mandrake7.2 gcc 2.95.3 (prerelease 1991030) - the default
compiler.

Thanks for any help :)
