[orbitcpp-list] warnings

[Laszlo M. <las...@et...>]

Hi Folks!

Some days ago I tried to investigate why gcc gives tons of warnings
during compilation of orbitc++ generated stuff. After I found the main
cause (those const/non const cast operators) I looked at some other
orbs how they solve this problem. I found special ifdefs in both mico
and omniorb, unfortunately none of those solutions were 100% perfect.
Anyway when I do something similar for orbitc++, I was not able to
compile everything :(

And unfortunately gcc 2.96 issues these warnings too :(

But there is another kind of warnings, which is caused by this
stuff in pass_stubs.cc:

void IDLPassStubs::doInterface(IDLInterface &iface)

[...]

       // make cast operators for all mi base classes
        IDLInterface::BaseList::const_iterator
        first = iface.m_all_mi_bases.begin(),last = iface.m_all_mi_bases.end();

        while (first != last) {
                m_header
                << indent << "operator " << (*first)->getQualifiedCPPIdentifier() << " &() {" << endl;
                m_header
                << ++indent << "return *" << (*first)->getQualifiedCPPCast("this") << ';' << endl;
                m_header
                << --indent << '}' << endl;
                first++;
        }

Here gcc says, that there is no point to provide

   operator Base&()

for the derived classes, because it won't execute them, but do the
right thing itself ;)

So I guess, this code could be safely removed.
