This PR breaks build with GCC 9 (for example gcc (Ubuntu 9.4.0-1ubuntu1~20.04.2) 9.4.0):

gcc -c -o ../build/ui.o ui/ui.c `pkg-config --cflags gtk+-3.0`
ui/ui.c: In function ‘stopHp’:
ui/ui.c:134:21: error: parameter name omitted

  713 | void* init_running_info(void *){
      |                         ^~~~~~
