206 They are in the process of being merged, but this is only a
207 preliminary, mechanical merging. Many definitions that are
208 identical between the two are still found in both versions.
210 The first version, with BFD_ASSEMBLER defined, uses high-level BFD
211 interfaces and data structures. The second version, with
212 BFD_ASSEMBLER not defined, also uses BFD, but mostly for swapping
213 data structures and for doing the actual I/O. The latter defines
214 the preprocessor symbols BFD and BFD_HEADERS. Try not to let this
217 These two are in the process of being merged, and eventually the
218 BFD_ASSEMBLER version should take over completely. Release timing
219 issues and namespace problems convinced me to merge the two
220 together in this fashion, a little sooner than I would have liked.
221 The real merge should be much better done by the time the next

232 Unfortunately, the common portions are very small at the moment,
233 and many declarations or definitions are duplicated. The structure
