+# SYNOPSIS
+#
+# AX_FUNC_SNPRINTF
+#
+# DESCRIPTION
+#
+# Checks for a fully C99 compliant snprintf, in particular checks whether
+# it does bounds checking and returns the correct string length; does the
+# same check for vsnprintf. If no working snprintf or vsnprintf is found,
+# request a replacement and warn the user about it. Note: the mentioned
+# replacement is freely available and may be used in any project
+# regardless of it's license.
