For testing i went to change flycheck-temp-file-system in flycheck.el
so that it reads

(setq tempfile (convert-standard-filename (expand-file-name
(file-name-nondirectory filename)
           directory)))

rather than the original

(setq tempfile (expand-file-name (file-name-nondirectory filename)
           directory))

I than edebugged the flycheck-temp-file-system with the
"c:/Users/guivh/emacs-guivho/.flycheck_emacs-guivho.org[*Org Src
emacs-guivho.org[ emacs-lisp ]*]") filename, and it nicely produced a
tempfile where the '*'s are replaced by '!'s.

Still, when editing elisp blocks from my elisp.org files, I keep
hitting the '*' problem...

Anyway, I do think that your suggestion is to the point, so I am going
to suggest it to the flycheck people. It certainly can't heart to call
this ectra function in non-windows ebvironments, as it doesn't do
anything there.

Thanks Eli,

Guido
