Thanks a lot for such detailed information, Ryan. It's going to be very
helpful. Yes, I'm going to do a private ports collection for just the
packages I need to cross-compile to Windows. I believe it can be a bit
difficult at the beginning, while I figure out how to do the plumbing, but
it will pay off in the long run, and it's exactly the approach I need.
By the way, I'm sorry for the delay in my reply: your message got into the
spam filter and I hadn't seen it :-(
Kind regards and thanks a lot,
