I was aware of http://www.muppetlabs.com/~breadbox/software/tiny/teensy.html when I found your repo, in the compose extends thread, so a bit of googling for a non-assembly based way, that seems easy to understand.

A standard static compile, with strip, was 750k or so on my machine.

The license on this example is public domain. I don't care what anyone does with it, there is nothing of value in any of this.
