Nautilus 2.2.0.2 doesn't build unless -O is used.  The reason is this line
in src/nautilus-server-connect.c:

  setlocale (LC_ALL, "");

The problem is that <libintl.h> only includes <locale.h> when __OPTIMIZE__
is defined.  I believe the correct solution to the problem is the following
patch:

--- nautilus-server-connect.c.old       2003-02-10 17:46:16.000000000 -0500
