All the prototypes and definitions following the comment "THE FOLLOWING IS EXTRACTED FROM THE SOURCE" are extracted from the source files for BFD. If you change it, someone oneday will extract it from the source again, and your changes will be lost. To save yourself from this bind, change the definitions in the source in the bfd directory. Type "make docs" and then "make headers" in that directory, and magically this file will change to reflect your changes. If you don't have the tools to perform the extraction, then you are safe from someone on your system trampling over your header files.
