Now everything is clear.  This is a bug in hexview-mode.el: reloading
files.elc is not a transparent action on MS-Windows, because doing so
removes some redefinition of functions necessary for the Windows port
of Emacs.  convert-standard-filename is just one of those functions;
there are others.

I suggest to report this as a bug to the maintainers of
hexview-mode.el.  At the very least, if they must re-load files.el,
they should on Windows after that re-load w32-fns.el and ls-lisp.el.
Preferably, hexview-mode.el should not re-load files.el at all.

system-type does not depend on the shell from which you invoke Emacs.
It depends on how your Emacs binary was built.  EmacsW32 is a native
Windows build, so its value of system-type should be windows-nt, no
matter what shell was used to launch it.

I will revert the changes made by Glenn in a day or two.

Thanks.
