While I am certain that the patch eliminates the duplicate symbols, I
am still concerned that assemble_external is being called with TREE_PUBLIC
and DECL_EXTERNAL set for the type declarations.  This causes .IMPORT
statements to be generated for the symbols under hpux.  While this appears
harmless under HPUX, I am not sure it would be under all circumstances.
It seemed to me that when there is no weak support these declarations
should not be external.  I remember there was some discussion of this
under AIX back in January.
