I've successfully build a 32-bit Emacs --with-wide-int on MS-Windows, for now _without_ NATIVE_FULL_AOT=1. . The built Emacs crashes on startup in interactive invocations from cmd.exe, if invoked as "emacs -Q" or "src/emacs -Q". This was traced to set_invocation_vars, which calls openp, which calls expand-file-name, which on MS-Windows expects the emacs_dir variable to be defined in the environment -- but this is false at that point, because init_environment was not yet called. I fixed this by avoiding the call to openp (MS-Windows executables have an easy way of determining their full absolute file name), but in general I must say that the call to init_vars_for_load in pdumper_load worries me quite a bit: this is a very early stage in startup, before we init most of our infrastructure, and so relying on file-name functions, memory allocation, etc. is very dangerous, especially on Windows, where the infrastructure not yet initialized at that point includes the environment. . After fixing the above, Emacs starts, but as soon as some simple command is invoked, and Emacs starts native-compiling Lisp packages, the Emacs subprocesses which run the async compilation start crashing. Not all of them crash, but some do. I wasn't yet able to find where they crash or why; stay tuned.
