Hi George,
I agree with all your points, besides,

In my previous mind, CPPFLAGS is only used for
preprocessor, you mean it is also used for C and C++
compiler?
(I think maybe you mean C and C++ compiler invokes C
preprocessor?)
Yeah - Anything that uses the preprocessor uses CPPFLAGS. The C and
C++ compilers always use the pre-processor, so they always use
CPPFLAGS.
Assembler files that end in .s don't use the preprocessor so they
don't use CPPFLAGS, but assembler files which end in .S use the
preprocessor, so they do use CPPFLAGS.
CPPFLAGS should only contain preprocessor options.
