The dump_macro() function fails to correctly output the definitions of macros that contain the string operator '#', the concatenation operator '##' and any macro parameter in the definition token list. For example, the following macros: #define STRING(x) #x #define CONCAT(x,y) x ## y are output like so: #define STRING(x) unhandled token type '21' #define CONCAT(x, y) unhandled token type '22' unhandled token type '23' unhandled token type '22' Add the code necessary to handle those token types to the dump_macros() function and add the above macros to the 'dump-macros.c' test file.
