This change is missing in the FSF changeLog.  (sorry but it is AFAIK a FSF
policy)

This function should be made `static' as I wrote before.

This declaration line should be removed completely as I wrote before.
write_exp_elt is not called from any other file so I find updating
a declaration which has no use anyway does not make much sense.

OK with these changes, if you follow the changes.
