Arsuino 1.8.1 Melzi board

I have a melzi board 1284p 8Mhz, blink test work OK. Trying to compile the Marlin I get:


Marlin:256: error: conflicting declaration of 'void enquecommand(const char*)' with 'C' linkage

So far this is my config

// Uncomment ONE of the next three lines - the one for your RepRap machine
//#define REPRAPPRO_HUXLEY
#define REPRAPPRO_MENDEL //Legacy Mendel
//#define REPRAPPRO_MENDEL2 // Mono Mendel

// Uncomment ONE of the next two lines - the one for your master controller electronics
#define REPRAPPRO_MELZI    // MELZI mco-mco
//#define REPRAPPRO_SANGUINOLOLU

// Uncomment ONE of the next two lines - the one for the series resistors on your controller
//#define SERIAL_R 4700
#define SERIAL_R 10000   // MELZI mco-mco

reprappro / Marlin
