[Consult] g++: About "-Wunused-variable" for constant variable initialized by function

[Chen Gang]

Is it correct?

This mailing list is for development of GCC, not the right place to learn
C++. Please ask either on gcc-help mailing list, or on some C++ user
forums.

OK, since I am not quite familiar with C++, can I still report the
related bug, and try to fix it?

If you worry about it, please help report the bug, and try to fix it.

Thanks.
