I found a problem about "Busy-wait delay loops".
Document says that to define F_CPU ,
 write "#define F_CPU 1000000UL  // 1 MHz" .
But it makes compile error when using makefiles that is 
made by Mfile.

Default, makefile has following definition.
F_CPU = 10000000
So if #define F_CPU is placed on our source file, double-definition error may
occur. It should be written in documentation.
