This changes stdin and stdout to be unbuffered	when they are tty's

 if (isatty(1))  
    (void)setvbuf(stdout, (char *)0, _IONBF, 0);
 if (isatty(0) && isatty(1)) { 
    (void)setvbuf(stdin, (char *)0, _IONBF, 0);

In the same way that in UNIX, but changing $(CC). You must create a file
called "makefile" (see below) and execute "make".

        HS   = f1.h f2.h f3.h etc...
        SRCS = f1.c f2.c f3.c etc...
        OBJS = f1.o f2.o f3.o etc...

        TOOL = example
        TRGT = $(TOOL).exe

        CC	= gcc

        .SUFFIXES : .o 
        .c.o:
        	$(CC) $(CFLAGS) -c $<

        CFLAGS  = -g

        $(TRGT): $(OBJS)
        	$(CC) $(CFLAGS) -o $(TOOL) *.o 
        	aout2exe $(TOOL)

        $(OBJS): $(HS) 

        clean:
        	del *.o
        	del $(TOOL)
