...and if he changes
GtkWidget *popup_menu_object;
to
extern GtkWidget *popup_menu_object;
in "gtk/menu.h", and puts
GtkWidget *popup_menu_object;
into "gtk/main.c", do the warnings go away?
(If so, then he probably has a compiler that, for
GtkWidget *popup_menu_object;
generates an external definition rather than an external reference, and
a linker that warns about multiple external definitions but treats them
as UNIX-style common definitions.)
These are good points. I think that you are right about the characteristics
of my compiler, but this is a standard linux system.
The relevant output from make is:
(cd .libs && gcc -c -fno-builtin -fno-rtti -fno-exceptions "etherealS.c")
rm -f .libs/etherealS.c .libs/ethereal.nm .libs/ethereal.nmS .libs/ethereal.nmT

If something wrong is happening (and I am not sure that it is) then
the configure script may need looking at.
I will check a number of points and answer all these issues later today.
Ben.
