@miran, I was looking at the changes and I believe these commits should be added in 1.6 (1.6.4):
* [Fix #19038 - making the Nim compiler work again on Windows XP](https://github.com/nim-lang/Nim/commit/c7d5b8c83ddf204c6e0cd7b6937d33318320ed91) * [Update manual.rst](https://github.com/nim-lang/Nim/commit/ef634cc2516ce81a05486f726e423ac458c4467a) * [fix 19292](https://github.com/nim-lang/Nim/commit/77ad8b81e414088c3116bf33f96efacd27eeb471) * [fix #19244 - solves the problem of the InAddr object constructor in Windows](https://github.com/nim-lang/Nim/commit/5ddaf3e1fbff4c0519088612f9ec3b10d62d2316) * [Making TCC work again on Windows --cpu:amd64 - fix #16326](https://github.com/nim-lang/Nim/commit/7806ec525eec83d250141a32cfa197949ea1a42b) I don't know very well the backport policy, but I believe it is convenient to add these corrections.
