I'm tring to use the IRIX C++ compiler v7.41 to build KDE-3.1.2. I'm
up to the kdenetwork module and have run into the following error
building kmail/kmmessage.cpp:
...

  The function "KMMimePartTree::itemClicked" is inaccessible.

    friend void KMMimePartTree::itemClicked( QListViewItem* item );
                                ^

                                ^

  The function "KMMimePartTree::slotSaveAs" is inaccessible.

    friend void KMMimePartTree::slotSaveAs();
                                ^

cc-3624 CC: WARNING File = kmfoldernode.h, Line = 57
  function "QObject::setName(const char *)" is hidden by "KMFolderNode::setName"
          -- virtual function override intended?

    void setName(const QString& aName) { mName = aName; }
         ^

cc-1682 CC: WARNING File = kmmsginfo.h, Line = 16
  The overloaded virtual function "KMMsgBase::setDate" is only partially
          overridden in class "KMMsgInfo".

  class KMMsgInfo: public KMMsgBase
        ^

I thought this was a bug in the IRIX C++ compiler so I created a small
test case to duplicate the bug and reported it to SGI:
  class Bar {
  protected:
    void test (int);
  };

  class Foo {
    friend void Bar::test (int num);
  };

According to SGI support, the compiler is correct. Here's what they
said:
  The access rules for friends has changed in the C++ language.
    See section 11.4 paragraph for the relevant information.

    One workaround is to replace
      friend void Bar::tests (int num);
    by
      friend class Bar;

So, how should I fix the above problem?
