Cleanup: Replace all uses of EXFUN in the BFD sources, with PARAMS.
* archures.c, reloc.c, section.c, tekhex.c: Use PARAMS in declaring pointers to functions. * cache.c, elf.c: Move static function decls to top, use PARAMS. * seclet.h: Declare external function with PARAMS. * libbfd.h: Update, based on changes in source code and chew.

|
||||
|
||||
* archures.c, reloc.c, section.c, tekhex.c: Use PARAMS in
|
||||
declaring pointers to functions.
|
||||
* cache.c, elf.c: Move static function decls to top, use PARAMS.
|
||||
* seclet.h: Declare external function with PARAMS.
|
||||
|
||||
* doc/chew.c (exfunstuff): Eliminate.
|
||||
(paramstuff): Replace exfunstuff with function to generate PARAMS.
|
||||
* doc/proto.str: Use paramstuff rather than exfunstuff.
|
||||
|
||||
* libbfd.h: Update, based on changes in source code and chew.
