PyErr_WarnEx should be used.  PyErr_Warn is just (see from Include/pyerrors.h):

#define PyErr_Warn(category, msg) PyErr_WarnEx(category, msg, 1)

If someone wants to remove the macro in 3k, go for it.  There are many
of these compatibility macros and stub functions left around for
binary compatibility.  We should try to get rid of those in 3k and
shrink the API.
