As I mentioned in my e-mail to you, I have not tried building WinCairo in 64-bit mode.

Since WebKit and all of the support libraries used in the WinCairo port are already being built under 64-bit operating systems, I don't think there are any fundamental barriers to doing so.

There may be parts of the WebKit Windows backend that are coded with 32-bit API calls, but this should be "a simple matter of programming" to identify and correct such instances.

The only wildcard I can think of is the pthreads library. However, I don't think there is anything fundamentally preventing this from being built for 64-bit OS.

I actually need to get this working in the medium term, so I'm excited to hear that someone else is looking into this.
