How about using -I option?

% global -xI die.h
die.h              42 gctags/C.c     #include "die.h"
die.h              42 gctags/Cpp.c   #include "die.h"
die.h              38 gctags/java.c  #include "die.h"
die.h              38 libutil/conf.c #include "die.h"
die.h              43 libutil/dbop.c #include "die.h"
...


By the way, I have found a bug about -I option.
I have already committed this patch.
