Luca,
I haven't looked at the code but here's some thoughts that popped to mind:
instead of printf() you could call ConsoleMessage() which is meant to show the message on non-console configurations (and default to printf on console configurations). Some configurations use statusbarHud.c which has a [!] menu button which then renders the messages as pixel text over the scene window. I think John gave the Android version a separate text window. 
If a return value would break something, could you do something like this: make that change but also change the name to int X3D_Initialize0() with a 0 in the name, and then make a function X3D_Initialize() with the old signature (that returns no value) and calls the 0() function? Then whoever can use the return value calls the 0 function and all the old code keeps calling the old way.
