+ Macros:
+ MID_WIDTH Medium width/precision positive integer constant. Choose

+ to be truncated for the conversions handled.
+ HUGE_WIDTH Large width/precision positive integer constant. Choose
+ such as to cause none of the strings produced to be
+ truncated for the conversions handled.
+ REF_FMT Reference output format string. Use no flags and such
+ a precision and length modifier, where applicable, and
+ a conversion as to make sure the output produced allows
+ the original value to be reproduced.
+ REF_VAL(v) Reference value V transformation. For conversions with
+ a truncating length modifier define such as to reproduce
+ the truncation operation, otherwise let V pass through.
+ PREC [optional] Working precision positive integer constant.
+ Set to the number of binary digits in the significand for
+ the argument type handled; usually for floating-point
+ conversions only, but it may be required for 128-bit or
+ wider integer data types as well.
+
+ Typedefs:
+ type_t Variadic function argument type. Define to the promoted
+ type corresponding to the conversion argument type
+ handled.
+
+ Variables:
+ vals Array of TYPE_T values. Choose such as to cover boundary
+ and any special cases.
+ length Length modifier string. Define according to the
+ conversion argument type handled.
+
+ The feature to be tested is wrapped into 'printf_under_test'. It is up
+ to the source including this skeleton if this is going to be a macro
