stat() in Cygwin currently returns a 32-bit value for file size, so there
is no support for correctly processing files over 2G in size.  This should
already be fixed in the recent snapshot of cygwin1.dll (actually, as soon
as ls is recompiled, IIUC).  Try installing the snapshot with the
appropriate headers, compiling ls from source, and see if it helps.
