#
# SYNOPSIS:
# AC_DEBUG
#
# DESCRIPTION:
# Adds support for the "--enable-debug" configure script option.
# If CFLAGS are not passed to configure, they will be set based
# on whether debugging has been enabled. Also, the NDEBUG macro
# (used by assert) will be set accordingly.
#
# WARNINGS:
# This macro must be placed after AC_PROG_CC or equivalent.
