Native compilation is unusable on 32-bit Cygwin, and this is reflected in the configure script. (See the --with-cygwin32-native-compilation configure option.) In the 64-bit case, Achim Gratz's autorebase postinstall script takes care of rebasing the .eln files on a regular basis, provided the user has set things up appropriately. Instructions can be found in the announcement at https://cygwin.com/pipermail/cygwin-announce/2022-April/010529.html In the 3 months since I sent that announcement, I have not heard from a single Cygwin user about rebase issues. This might simply mean that very few users have tried the native compilation release. I myself use that release daily, and I can only recall one instance in which I saw a fork failure and had to exit emacs and rebase. In summary, I would say that native compilation is usable with very occasional minor annoyances on 64-bit Cygwin. But I doubt if I will ever make it the default Cygwin build, simply because I don't want to be inundated with emails from people who haven't read the release announcement. Ken
