Installed on cygwin the emacs-w32.exe version, do you mean that?  This
Emacs built (version emacs-27.0.90) is knowing w32-shell-execute. :-)

But now there is the problem that w32-shell-execute seemingly doesn't
recognise cygwin paths. (here: "/cygwin/c/...")

  error "ShellExecute failed: The system cannot find the file..."

It seems to me as if w32-shell-execute is not literate for cygwin paths
and one needs to normalise them to the Windows standard ("c:/...")?

Thank you Eli
