I now understand why it works on my machine and not on my colleague's:

On my colleague's machine c:\tcl\bin is the first element in path, and
this gets thus mangled by setting the path with a ':' separator and thus
the tclsh or wish executable isn't found any more. On my machine there is
something else before c:\tcl\bin and so this doesn't get mangled and the
executable still is found.

This is not a problem in msys as the path is set *nix style.

Is there a way to tell within tcltk whether we are in windows or in *nix
path mode and thus to conditionalise the setting of the path ? Or to
rewrite the expression so that it works everywhere ?
