Progress report:
. 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.
