From 6bb99757b780144d9fa27cdce09d3621e1a0ed43 Mon Sep 17 00:00:00 2001 From: Josh de Kock Date: Sat, 26 Mar 2016 15:27:23 +0000 Subject: jack: Support OSX Previously, with JACK installed, the configure script would enable the JACK indev; this broke on OS X due to an incomplete pthreads implementation. Add some simple macros to map libdispatch to pthreads on OS X.
