Revision: 50 http://trac.macosforge.org/projects/libdispatch/changeset/50 Author: robert@fledge.watson.org Date: 2009-10-03 06:31:32 -0700 (Sat, 03 Oct 2009) Log Message: ----------- Detect pthread_main_np() in configure, and only use if defined. For non-supporting platforms, it would be advantageous to provide a compat interface.
