Is it practical for non-conforming implementations of printf to be proxied
- so part of the customization process when porting lwIP to your platform
would be to review a list of in-use format specifiers and then implement a
proxy which maps those to whatever your platform needs before calling your
own printf function.

Obviously this would require that your compiler supports varargs
processing and that you have a va_printf sort of function.

Just a suggestion.

Best wishes,
