  25 /* bfd.h -- The only header file required by users of the bfd library
  26
  27 The bfd.h file is generated from bfd-in.h and various .c files; if you
  28 change it, your changes will probably be lost.
  29
  30 All the prototypes and definitions following the comment "THE FOLLOWING
  31 IS EXTRACTED FROM THE SOURCE" are extracted from the source files for
  32 BFD.  If you change it, someone oneday will extract it from the source
  33 again, and your changes will be lost.  To save yourself from this bind,
  34 change the definitions in the source in the bfd directory.  Type "make
  35 docs" and then "make headers" in that directory, and magically this file
  36 will change to reflect your changes.
  37
  38 If you don't have the tools to perform the extraction, then you are
  39 safe from someone on your system trampling over your header files.
  40 You should still maintain the equivalence between the source and this
  41 file though; every change you make to the .c file should be reflected
  42 here.  */

 436    The CAT4 hack is to avoid a problem with some strict ANSI C preprocessors.
 437    The problem is, "32_" is not a valid preprocessing token, and we don't
 438    want extra underscores (e.g., "nlm_32_").  The XCAT2 macro will cause the
 439    inner CAT macros to be evaluated first, producing still-valid pp-tokens.
 440    Then the final concatenation can be done.  (Sigh.)  */
