gtkmm WARNING: yesterday's CVS vers. needs -pedantic with egcs-1.1

[Christof Petig <christof petig wtal de>]

Hello,

after three hours of bug hunting (I first checked the cpp
output)(gtkmm's examples linked, my progs not) I found the -pedantic
flag as the cause.

So if you get link errors like
   /home/christof/cvs/gtk/Search_ComboBox.cc
(.Connection gnu.linkonce.t.connect_to_method<_GtkObject,
SearchComboBox>
(Signal_proxy0<_GtkObject> &, SearchComboBox *, SearchComboBox *,
                void (SearchComboBox *))+0x98):
undefined reference to `Gtk_Object::signal_connect(char const *, void
(*)(...), void *)'

simply add -pedantic.

The correct funtion is:
  Gtk_Object::signal_connect(char const *, void (*)(void), void *)
instead of
  Gtk_Object::signal_connect(char const *, void (*)(...), void *)

I'd be grateful for any explanation by C++ wizards. Sigh.

Christof

PS: Quoting from the (old) gcc man page:
              Valid ANSI standard C programs should compile prop­
              erly with or without this option (though a rare few
              will  require  `-ansi').  However, without this op­
              tion, certain GNU extensions and traditional C fea­
              tures  are  supported  as  well.  With this option,
              they are rejected.  There is no reason to use  this
              option; it exists only to satisfy pedants.
