|HI,
|When I run gcc on some source here I get this error:
|
|/usr/include/obj_ext.h:5: warning: useless keyword or type name in empty declaration
|/usr/include/obj_ext.h:6: warning: useless keyword or type name in empty declaration
|/usr/include/obj_ext.h:7: warning: useless keyword or type name in empty declaration
|/usr/include/obj_ext.h:8: warning: useless keyword or type name in empty declaration
|/usr/include/obj_ext.h:9: warning: useless keyword or type name in empty declaration
|
|and the corresponding source is
|
|extern struct obj;
|extern struct obj;
|extern struct obj_type;
|extern struct obj_type;
|extern struct obj_list;
|extern struct obj_list;

The extern is a 'useless keyword' in an 'empty declaration'.

It has no meaning whatsoever.

You can save 7 bytes of space by deleting it.  Think of all the baby
bytes that will be so happy that their mommy or daddy was not
sacrificed (oops, sorry...  :-)

If you had typed

extern struct obj foo;

then the extern would have a non empty declaration to refer to (the foo).

but

extern struct obj;

really has absolutly no meaning what so ever.

Other C compilers simply ignore it; gcc 2.x.x warns about it.
