Otherwise, nothing is added. -# -# Define the variables listed in the second argument if debug is enabled, -# defaulting to no variables. Defines the variables listed in the third -# argument if debug is disabled, defaulting to NDEBUG. All lists of -# variables should be space-separated. -# -# If debug is not enabled, ensure AC_PROG_* will not add debugging flags. -# Should be invoked prior to any AC_PROG_* compiler checks. -# -# IS-RELEASE can be used to change the default to 'no' when making a -# release. Set IS-RELEASE to 'yes' or 'no' as appropriate.
