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
CDEFS = -DF_CPU=$(F_CPU)UL
So if #define F_CPU is placed on our source file, double-definition error may occur. It should be written in documentation.
