++# 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.
