In Python for example, one can use

Alternatively, if we can't come to an agreement on whether this is a good idea or how to provide this function to users reliably, maybe we can at least provide some boilerplate code that users can paste to check for a program with or without a file extension at run time.

Please provide a function that users and third-party packages can rely on inside of Octave to get the suffix / file extension for executable programs.

For example, on Unix and GNU/Linux operating systems this would return the empty string, and on Windows this would return '.exe'.

Inside of Octave, m-file functions use

This works fine for Octave itself, but is not a function that should be relied on for code outside of Octave. So Octave should provide an equivalent that can be used safely.

As a motivating example, the Octave Forge package 'miscellaneous' shells out to the program 'units'. It has a check that the executable 'units' exists in PATH, but it has to append EXEEXT to ensure that it works on Windows.
