Just a complete SWAG, but I would expect that functions would be probably
be declared in one pass, and execution happen in another pass. So I would
not expect to be able to compile the function at script execution time. Maybe
declare two functions, and call one or the other at runtime based on ${OS}.

Or write the script in perl. Or Smalltalk with CommandShell/OSProcess.
