That's a feature.  The DJGPP (and Windows 9X/NT) version of Emacs doesn't
spawn `ls' to create the directory listing; instead, it uses some Lisp
code that calls the `file-attributes' primitive (see the files dired.c and
ls-lisp.el).  And `file-attributes' deliberately converts any size that's
larger than what Emacs can handle to -1.  Since Emacs integers are 28-bit
wide, you actually get -1 even before you hit 2GB.  128MB is the largest
file Emacs can edit.
