-All the prototypes and definitions following the comment "THE FOLLOWING

-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

-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.
-You should still maintain the equivalence between the source and this
-file though; every change you make to the .c file should be reflected
