Well it does it in a different way:

objc-api.h: objc_EXPORT IMP (*__objc_msg_forward)(SEL);

and objc_EXPORT is defined in objc-decls.h as

#  define objc_EXPORT  __declspec(dllexport)

(as long as you define BUILD_libobjc_DLL on the compile line)
which should do the same thing as adding it to the defs file.

 ). I tried also gcc-2.95.3+gnustep-libobjc pair with the same result. I

Can you try instead:

 extern __declspec(dllimport) IMP (*__objc_msg_forward)(SEL);

???
