TINY_PRINTF is meant to be tiny, i.e. not consume a lot of space, at the 
expense of functionality. This is meant to be used in size constrained 
environments, like the SPL. If you need full vsprintf() formatting 
support, disable TINY_PRINTF in your config and use the regular 
vsprintf() implementation.
