|> 
|> 	Change line #12 from: splitfont $(FONT) to: ./splitfont $(FONT)
|> 	Change line #24 from: font.bin: font_2_bin $(RAWFONT) 
|> 			  to: font.bin: ./font_2_bin $(RAWFONT)
|> 
|> 10: Edit src/display/d.profile/main.c
|> 
|> 	Change line #352 from: cfree(profile.ptr); to: free(profile.ptr);
|> 
|> 11: Edit src/imagery/i.class/zoom_box.c and
|>          src/imagery/i.points/zoom_box.c

|> 	Declare the following statements before the zoom_box() function:
|> 
|> 	static int cancel();
|> 	static int zoom1();
|> 	static int zoom2();
|> 
|> 	and remove int cancel(); and int zoom1(); from within the zoom_box()

|> #include "globals.h"

|> 
|> static int x1, y1, x2, y2;
|> static View *pick_view, *zoom_view, *main_view;

|> zoom_box()

|>     static int use = 1;
|>     static Objects objects[]=
|>     {
|> 	MENU("Cancel",cancel,&use),
|> 	INFO(" Mark first corner of window ",&use),
|> 	OTHER(zoom1,&use),
|> -----------------------------------------------------------------------------
|> 
|> 12: Edit src/imagery/i.target/ask_target.c
|> 
|> 	Change line #11 from: strcpy(cur_location, location, cur_location);
