Revision: 20 http://trac.macosforge.org/projects/libdispatch/changeset/20 Author: robert@fledge.watson.org Date: 2009-09-13 10:08:49 -0700 (Sun, 13 Sep 2009) Log Message: ----------- Add --without-libdispatch-init-constructor in order to disable tagging of libdispatch_init as a constructor. On most systems, it is required, but for the Mac OS X libSystem, the init routine is run during process startup by libsyscall. While it's unlikely users will want to configure this with the autoconf build, the Mac OS X build will want to set this generated variable in the hard-coded config.h for Xcode.
