Thank you HazardsMind! I updated my UTFT library provided by Henning Karlson, and that fixed my problems with compiling your examples.
Something that my be helpful for other people using your examples would be this bit of commenting, and code that was provided with the UTFT library.
// Uncomment the next two lines for the Arduino 2009/UNO
//UTFT myGLCD(ITDB24D,19,18,17,16); // Remember to change the model parameter to suit your display module!
//UTouch myTouch(15,10,14,9,8);
// Uncomment the next two lines for the Arduino Mega
UTFT myGLCD(ITDB32S, 38,39,40,41); // Remember to change the model parameter to suit your display module!
UTouch myTouch(6,5,4,3,2);
Thank you for your work! It will really help me make some nice display screens!
