My best guess is that the problem is right inside the file IRremoteInt.h
EDIT: Sirbow2 got the answer in just before me. His would probably work better.
Open up that file with wordpad and find the line that says
#include <WProgram.h>
and change it to
#include <Arduino.h>
as mentioned in your post.
The file is located at C:\Users\Robert\Desktop\arduino-1.0\libraries\IRremote
This seems to be the problem because the compiler is outputting: ...IRremoteInt.h:15:22: error: WProgram.h: No such file or directory
After you do that, the library should be compatible with Arduino 1.0 and usable with your current code.
