gtk+ предупреждения при компиляции

Не пинайте если что, только начинаю осваивать GTK+

Ну вообщем при компиляции выскакивает много предупреждений типа:

gcc -c gfim.c `pkg-config --cflags --libs gtk+-2.0` -D_debug -Wall
gfim.c: In function ‘main’:
gfim.c:28: warning: assignment makes pointer from integer without a cast
gfim.c:29: warning: comparison between pointer and integer
gfim.c:38: warning: passing argument 1 of ‘close’ makes integer from pointer without a cast
