Thank you.
If the command layer parser becomes discontinued, I would like to fix the buf 
like this.

Change:
=======
[main() in gtags.c]

        if (iflag && (!test("f", makepath(dbpath, dbname(GTAGS), NULL)) ||
                !test("f", makepath(dbpath, dbname(GRTAGS), NULL)) ||       <= 
ADDED
                !test("f", makepath(dbpath, dbname(GPATH), NULL)))) {
                if (wflag)
                        warning("GTAGS, GRTAGS or GPATH not found. -i option 
ignored."); <= CHANGED
                iflag = 0;
        }

The result:
===========

$ gtags -wi
Warning: GTAGS, GRTAGS or GPATH not found. -i option ignored.
