No, you quoted it wrong. That sentence is describing the difference between AC_DEFUN and m4_define (not m4_defun). m4_define is low-level (create a definition, but no hooks for ordering); m4_defun is higher-level (create a definition AND include hooks for ordering constraints in that definition). -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3266 Virtualization: qemu.org | libvirt.org
