+# SYNOPSIS
+#
+#   AX_C_VAR_FUNC
+#
+# DESCRIPTION
+#
+#   This macro tests if the C complier supports the C9X standard __func__
+#   indentifier.
+#
+#   The new C9X standard for the C language stipulates that the identifier
+#   __func__ shall be implictly declared by the compiler as if, immediately
+#   following the opening brace of each function definition, the declaration
+#
+#       static const char __func__[] = "function-name";
+#
+#   appeared, where function-name is the name of the function where the
+#   __func__ identifier is used.
