        Modifications to Allow symbolic links.
        
        I have modified global(1) and gtags(1) to allow symbolic link.
        To realize it, I used normalize_path() and abs2rel() in 
libutil/abs2rel.c
        module instead of realpath(3) library function.
        
        Though the symbolic link to a directory might confuse users,
        it is originally as such. They should understand the characteristic.

        /tmp

          |  +-GTAGS
          |  +-gtags ----+ (symbolic link to ../work/gtag2)
          |  +-htags --+ | (symbolic link to ../work/htag2)
          |            | |
