# 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.
