Aby som bol kokretny takto vyzera vystup make  pri pokuse o kompilovanie
X-Win SW, pozostavajuceho s 7 fullscreen obrazoviek pre X,ktory robi ten
nezmysel...

gcc -ggdb3    -O2 -fno-strength-reduce     -I/usr/X11R6/include  -I/usr/X11R
6/include  -Dlinux -D__i386__ -D_POSIX_C_SOURCE=199309L -D_POSIX_SOURCE -D_X
OPEN_SOURCE=500L -D_BSD_SOURCE -D_SVID_SOURCE   -DFUNCPROTO=15 -DNARROWPROTO
     -c obrazky.c -o obrazky.o
rm -f pokus
gcc -ggdb3    -o
okus -O2 -fno-strength-reduce      -L/usr/X11R6/lib  -L/usr/X11R6/lib
obrazky.o -lXm -lXt -lSM -lICE -lXp -lXext -lX11  -lXaw -lm -lXmu -lXt -lSM 
-lICE -lXext -lX11 -L/usr/X11R6/lib
