The Windows build is broken again. It seems likely one of the recent
commits affecting file error codes is the culprit. The build fails here:

rm -f bootstrap-emacs.pdmp
./temacs --batch  -l loadup --temacs=pbootstrap
emacs: Testing file: Permission denied,
c:/projects/emacs/share/emacs/27.0.50/etc/NEWS
make[1]: *** [Makefile:817: bootstrap-emacs.pdmp] Error 1
make[1]: Leaving directory '/c/projects/emacs/src'
