Usage under MS Windows

I changed the windowdir function to:

" windowdir
"  Gets the directory for the file in the current window
"  Or the current working dir if there isn't one for the window.
"  Use tr to allow that other OS paths, too
function s:windowdir()
  if winbufnr(0) == -1
    let unislash = getcwd()
  else
    let unislash = fnamemodify(bufname(winbufnr(0)), ':p:h')
  endif
  return tr(unislash, '\', '/')
endfunc

Auto Update Database

" If you set this to 1, it will auto update your cscope/gtags database and
" reset the cscope connection when you save a file.
if !exists("g:autocscope_auto_update")
  let g:autocscope_auto_update = 1
endif


function s:Update_csdb()
    if g:autocscope_auto_update != 1
      return
    endif

    if exists("b:csdbpath")

              exe "silent !cd " . b:csdbpath . " && global -u"

Support for GNU GLOBAL

" If you set this to 1, it will use gtags-cscope instead of cscope which is
" faster than cscope.
if !exists("g:autocscope_use_gtags")
  let g:autocscope_use_gtags = 1
endif


if g:autocscope_use_gtags == 1
    let g:autocscope_tagfile_name = "GTAGS"
    set cscopeprg=gtags-cscope
else
    let g:autocscope_tagfile_name = "cscope.out"
    set cscopeprg=cscope
endif

In function Cycle_csdb: When use gtags-cscope, should change to the directory that contains the dbs first.

Change:

    exe "cs add " . b:csdbpath . "/cscope.out " . b:csdbpath

to:

    exe "cd " . b:csdbpath
    exe "cs add " . b:csdbpath . "/" . g:autocscope_tagfile_name . " " . b:csdbpath

Then replace "out", "cscope.out" with g:autocscope_tagfile_name at other places.
