+ This file really contains two implementations of the COFF back end.

+ 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.
