Thread: Building GCC 10.x warning question.

Code:

../../gcc-git/gcc/cp/coroutines.cc:2700:22: warning: defaulted and deleted functions only available with '-std=c++11' or '-std=gnu++11'
 2700 |   var_nest_node () = default;

gcc/coroutines.cc at master * gcc-mirror/gcc * GitHub

I am building a very recent (less than one week old) MinGW64 GCC for MSys2 (an cygwin clone) for 32 and 64 bit MinGW GCC work.

And, I got over an thousand warnings at first; I am now trying to reduce the warnings by removing or ignoring the un-important ones.

I have no idea if this is one to ignore or try to fix.

Can someone tell me which it is?
