Log message:
        BUGFIX: When empty file exists, `global -g' fails.
        
                $ touch a.c
                $ gtags
                $ global -g foo
                global: mmap failed (./a.c).
        
        POSIX says `If len is zero, mmap() shall fail and no mapping shall be 
established.'
