RH		 209 They are in the process of being merged, but this is only a
210 preliminary, mechanical merging. Many definitions that are
211 identical between the two are still found in both versions.
212
213 The first version, with BFD_ASSEMBLER defined, uses high-level BFD
214 interfaces and data structures. The second version, with
215 BFD_ASSEMBLER not defined, also uses BFD, but mostly for swapping
216 data structures and for doing the actual I/O. The latter defines
217 the preprocessor symbols BFD and BFD_HEADERS. Try not to let this
218 confuse you.
219
220 These two are in the process of being merged, and eventually the
221 BFD_ASSEMBLER version should take over completely. Release timing
222 issues and namespace problems convinced me to merge the two
223 together in this fashion, a little sooner than I would have liked.
224 The real merge should be much better done by the time the next
225 release comes out.
226
227 For now, the structure of this file is:
228 <common>
229 #ifdef BFD_ASSEMBLER
230 <one version>
231 #else
232 <other version>
233 #endif
234 <common>
235 Unfortunately, the common portions are very small at the moment,
236 and many declarations or definitions are duplicated. The structure
237 of obj-coff.c is similar.
238
239 See doc/internals.texi for a brief discussion of the history, if
240 you care.
