+# SYNOPSIS

+# AC_CHECK_DEFINE([symbol], [ACTION-IF-FOUND], [ACTION-IF-NOT])
+# AX_CHECK_DEFINE([includes],[symbol], [ACTION-IF-FOUND], [ACTION-IF-NOT])
+#
+# DESCRIPTION
+#
+# Complements AC_CHECK_FUNC but it does not check for a function but for a
+# define to exist. Consider a usage like:
+#
+# AC_CHECK_DEFINE(__STRICT_ANSI__, CFLAGS="$CFLAGS -D_XOPEN_SOURCE=500")
