Nope, thank you.  Look at this:

  D:\Home\dexcoff1\dexcoff1\cygwin2011f\bin\cygiconv-2.dll
  \\?\D:\Home\dexcoff1\dexcoff1\cygwin2011f\bin\cygiconv-2.dll

So it's the same DLL path, just one time with the long pathname prefix
(or better: The Win32 equivalent to the native NT path prefix).  But,
as I wrote in my mail to Heiko, neither the Windows loader nor the
GetModuleFileName call normalize the path.  So I think I just apply
my patch to use only the basename in the dll_init code.


Thanks,
Corinna
