Disable warning about explicitly initializing base constructor inside copy constructor of derived class

Question

I\'m using g++ version 4.2.1 with -Wextra enabled. I\'m including a header from a library, and I keep getting the following warning about a class in the library, which is enable

Answer 1

According to http://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html (search for Wextra) that is an inherent part of -Wextra and can't be disabled separately (e.g. it isn't listed separately by its own -W option).

It looks like the best you can do is either isolate the use of the library to one file on which you disable -Wextra or don't use -Wextra at all and individually enable all its components (from that link).
