+/* ***********************************************************************
+
+   This file really contains two implementations of the COFF back end.
+   They are in the process of being merged, but this is only a
+   preliminary, mechanical merging.  Many definitions that are
+   identical between the two are still found in both versions.
+
+   The first version, with BFD_ASSEMBLER defined, uses high-level BFD
+   interfaces and data structures.  The second version, with
+   BFD_ASSEMBLER not defined, also uses BFD, but mostly for swapping
+   data structures and for doing the actual I/O.  The latter defines
+   the preprocessor symbols BFD and BFD_HEADERS.  Try not to let this
+   confuse you.
+
+   These two are in the process of being merged, and eventually the
+   BFD_ASSEMBLER version should take over completely.  Release timing
+   issues and namespace problems convinced me to merge the two
+   together in this fashion, a little sooner than I would have liked.
+   The real merge should be much better done by the time the next
+   release comes out.
+
+   For now, the structure of this file is:
+	<common>
+	#ifdef BFD_ASSEMBLER
+	<one version>
+	#else
+	<other version>
+	#endif
+	<common>
+   Unfortunately, the common portions are very small at the moment,
+   and many declarations or definitions are duplicated.  The structure
+   of obj-coff.c is similar.
+
+   See doc/internals.texi for a brief discussion of the history, if
+   you care.
