+# AX_CHECK_ENABLE_DEBUG([enable by default=yes/info/profile/no], [ENABLE DEBUG VARIABLES ...], [DISABLE DEBUG VARIABLES NDEBUG ...], [IS-RELEASE])

+# DESCRIPTION
10
+#
11
+# Check for the presence of an --enable-debug option to configure, with
12
+# the specified default value used when the option is not present. Return
13
+# the value in the variable $ax_enable_debug.
14
+#
15
+# Specifying 'yes' adds '-g -O0' to the compilation flags for all
16
+# languages. Specifying 'info' adds '-g' to the compilation flags.
17
+# Specifying 'profile' adds '-g -pg' to the compilation flags and '-pg' to
18
+# the linking flags. Otherwise, nothing is added.
19
+#
20
+# Define the variables listed in the second argument if debug is enabled,
21
+# defaulting to no variables. Defines the variables listed in the third
22
+# argument if debug is disabled, defaulting to NDEBUG. All lists of
23
+# variables should be space-separated.
24
+#
25
+# If debug is not enabled, ensure AC_PROG_* will not add debugging flags.
26
+# Should be invoked prior to any AC_PROG_* compiler checks.
27
+#
28
+# IS-RELEASE can be used to change the default to 'no' when making a
29
+# release. Set IS-RELEASE to 'yes' or 'no' as appropriate. By default, it
30
+# uses the value of $ax_is_release, so if you are using the AX_IS_RELEASE
31
+# macro, there is no need to pass this parameter.
32
+#
33
+# AX_IS_RELEASE([git-directory])
