Redirecting printf() does not work

Thank you
The PUTCHAR_PROTOTYPE function is in my main.c file. In fact all the code is in main.c
I was thinking about compiler options cause in this part :

#ifdef __GNUC__
/* With GCC/RAISONANCE, small printf (option LD Linker->Libraries->Small printf
   set to 'Yes') calls __io_putchar() */
#define PUTCHAR_PROTOTYPE int __io_putchar(int ch)
#else
#define PUTCHAR_PROTOTYPE int fputc(int ch, FILE *f)
#endif /* __GNUC__ */


it says: With GCC/RAISONANCE, small printf (option LD Linker->Libraries->Small printf set to ‘Yes’) calls __io_putchar()
Which I’m not sure what it’s talking about ...
And the fact that this all worked in Keil that first time.
