RH		 199 They are in the process of being merged, but this is only a
200 preliminary, mechanical merging. Many definitions that are
201 identical between the two are still found in both versions.
202
203 The first version, with BFD_ASSEMBLER defined, uses high-level BFD
204 interfaces and data structures. The second version, with
205 BFD_ASSEMBLER not defined, also uses BFD, but mostly for swapping
206 data structures and for doing the actual I/O. The latter defines
207 the preprocessor symbols BFD and BFD_HEADERS. Try not to let this
208 confuse you.
209
210 These two are in the process of being merged, and eventually the
211 BFD_ASSEMBLER version should take over completely. Release timing
212 issues and namespace problems convinced me to merge the two
213 together in this fashion, a little sooner than I would have liked.
214 The real merge should be much better done by the time the next
215 release comes out.
216
217 For now, the structure of this file is:
218 <common>
219 #ifdef BFD_ASSEMBLER
220 <one version>
221 #else
222 <other version>
223 #endif
224 <common>
225 Unfortunately, the common portions are very small at the moment,
226 and many declarations or definitions are duplicated. The structure
227 of obj-coff.c is similar.
228
229 See doc/internals.texi for a brief discussion of the history, if
230 you care.
