It follows Eli's > suggestion of using 'Fw32_long_file_name'. The patch looks good - please apply it. I tried building with the patch applied to a clean tree, and the resulting emacs runs without the filename mismatch messages, and did not recompile the AOT files into the per-user eln-cache. There were also a couple of errors in the build: Backtrace: 00007ff78467a2a2 00007ff78453be26 00007ff7845a98ac ...[snipped]... 00007ff784626548 Eager macro-expansion failure: (file-error "Renaming" "Permission denied" "c:/emacs/git/emacs/native/build/mingw64-x86_64-O2-native/native-lisp/28.0.50-e09cfb99/cc-bytecomp-4817e810-d16f606e.eln" "c:/emacs/git/emacs/native/build/mingw64-x86_64-O2-native/native-lisp/28.0.50-e09cfb99/cc-bytecomp-4817e810-d16f606e.elnGMMUdn.eln.tmp") C:/emacs/git/emacs/native/src/alloc.c:3160: Emacs fatal error: assertion failed: cu->handle make[2]: *** [Makefile:319: progmodes/antlr-mode.elc] Error 3 The backtrace addresses did not give anything useful from addr2line.
