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;


My question is: how do I turn this warning off while keeping other
warnings on?? I get at least 25 such warnings from the include file in
question (a part of extended COFF support for a DEC Station/MIPS
machine running ULTRIX), which of course screws me over, and I have to
do gcc -w.

I hate working with all the warnings turned off, and its impossible to
run with warnings enabled because I am sure to get at least a 100 when
I do a make.  I want to use -Wall, but to be able to turn off this
*one* warning. I looked in the man/info pages, and could not find a
clue.

I would appreciate any help at all. I am using gcc v.2.3.3.
