This is not 64 bits. i686-w64-mingw32 is 32 bits. But for this, I 
adapted some patches borrowed from bug #5179, that may interest you.

Here is the way I follow in order to install everything.
(I have scripts for this, but they are not generic…)

First, install cygwin, with something like this:

00_install_suite.sh is something like that:

where installation_configuration.sh contains some functions and variables:

Flexlink is a patched version (see bug #5179)

If somebody wants them, I can share those recipes.
