 With the 64-bit version of OSGeo4W, I'm seeing overflow with the `ls`
 utility while inspecting files larger than 4 GB. For instance, write three
 files that are near the 4 GB size where this is an issue, e.g. with Python
 {{{
 import os
 os.chdir(r'C:\temp')
 with open('f1.tmp', 'wb') as f:
     f.write(b'\x00' * (2 ** 32 - 1))
 with open('f2.tmp', 'wb') as f:
     f.write(b'\x00' * (2 ** 32))
 with open('f3.tmp', 'wb') as f:
     f.write(b'\x00' * (2 ** 32 + 1))
 }}}
 Now with either MSYS or the CMD.EXE-based OSGeo4W Shell (shown):
 {{{
 C:\Temp>dir *.tmp
  Volume in drive C is Windows
  Volume Serial Number is C0A8-5CF4

  Directory of C:\Temp

 26/01/2015  02:27 p.m.     4,294,967,297 f3.tmp
                3 File(s) 12,884,901,888 bytes
                0 Dir(s)  13,467,774,976 bytes free

 C:\Temp>where ls
 C:\OSGeo4W\apps\msys\bin\ls.exe
 }}}

 Other tools like `wc` show the correct number of bytes, so I'm not sure
 where the issue is exactly or what other tools to check. I haven't checked
 with the 32-bit version of OSGeo4W either.
