I don't think naming the file MonoPosixHelper.dll is incorrect. It's a
native Windows DLL and Windows has the naming convention *.dll without any
prefixes. Using the prefix lib for Windows DLL is useless but using the
prefix cyg is funny because it does not depend on Cygwin.

I don't think the problem is the modified libtool code because I use it as
well but no MonoPosixHelper-0.dll is created for me. In the installer there
are MonoPosixHelper.dll and MonoPosixHelper-0.dll as well, but
MonoPosixHelper-0.dll is not used by the binaries and can be removed without
any problems.

In the installer MonoPosixHelper.dll and MonoPosixHelper-0.dll are two
different libraries, and there is significant difference in their size as

So I still don't know what MonoPosixHelper-0.dll is.
