Thanks. But what does it mean "on Cygwin" in this context? If you
are building with the MinGW64 tools, what Cygwin has got to do with
this?

They are helpful, but I have a few questions:

What was wrong with the original code, and why did you need to move
the definition of _WIN32_IE further down? What error messages did you
see with the original code?

This breaks the MinGW32 build, so please see if the current trunk has
a better solution for this problem.
