Compiling with compaq cxx

[Jean-Marc Lasgouttes]

When I compile latest cvs with cxx, I get lots of

cxx: Error: ../../../../lyx-devel/src/frontends/xforms/FormFiledialog.C, line 407: 
          identifier "slot" is undefined
        r_ = Dialogs::redrawGUI.connect(slot(this, &FileDialog::Private::redraw));
----------------------------------------^


I guess it is related to the recent namespace changes. So, how is
the compiler supposed to find out that slot is really SigC::slot?
