libsamplerate/examples/audio_out.c fails on newer MacOS (#28)

Currently, we patch away the libsamplerate examples.
That saves as a second of compilation time, but more importantly,
it allows the port to build, as there is no Carbon.h on e.g. 10.13.2

Could someone please point me to a documantation of the various
audio subsystem MacOS has used since (say) 10.5.8, and the history?

	Thank you
