+DESCRIPTION
+       Copy private BFD header information from the BFD @var{ibfd} to the
+       the BFD @var{obfd}.  This copies information that may require
+       sections to exist, but does not require symbol tables.  Return
+       <<true>> on success, <<false>> on error.
+       Possible error returns are:
+
+       o <<bfd_error_no_memory>> -
+       Not enough memory exists to create private data for @var{obfd}.
