One extra thing to update:

after changing the two instances you mentioned I got this error, so I also added the lines if displaytype == 3 etc. there
now it's compiling

Code:

/home/erik/Arduino/WeatherDuino_P2AT2560_RX_v8.2_b001/Routines.ino: In function 'void RunEvery_1_Minute()':
Routines:374:42: error: 'update_BigClock' was not declared in this scope
  if (activeWindow == 8) update_BigClock();

                                         ^
exit status 1
