Emacs UI: set back "cocoa5-executable" to "CoCoAInterpreter"?

Description

In earlier versions cocoa5-executable was CoCoAInterpreter.
Now it is the script cocoa5 (and this caused problems on Windows because scripts do not work there).

The cocoa5 script works very well for calling the command-line version from any directory.
But this is not necessary for emacs (because emacs needs to be configured anyway).
So, we cannot remember why we did this change: probably to allow spaces in path.

Proposal: change back and test with spaces in path. If it works we can unify Mac/Linux and Windows EmacsUI settings.

Rejected: the script cocoa5 is used on linux to choose the executable 32/64 bit (May also be used similarly on Mac).

We remembered! in linux the cocoa5 script makes an automatic choice between 32 and 64 bit executable.

All modern Macs are 64 bits, but the same mechanism can be used for choosing between versions (for example for different MacOS's).

What to do for minimizing the differences with the Windows version then?
I'll think about it....

JAA notes that Emacs lisp has the built-in variable system-type which gives information about which OS is running. This could be used to pass the --packageDir parameter only on Microsoft systems.

ok, I used it and it works.

My attempt at just modifying cocoa5.emacs did not work, as John had guessed:
setting cocoa5-executable to "../CoCoAInterpreter --sakshf" gives
