Hi all,
I am trying to build GCC 10.2 using Ubuntu's Arm cross compiler.
But I am getting the following error,
../../../../../gcc-10.2.0/libstdc++-v3/src/c++17/memory_resource.cc:92:5: error: ‘__constinit’ does not name a type

It looks like build is failing because it is trying to build a C++ 17 feature using a C++ 20 keyword. I am not sure what to do from here, any help is greatly appreciated .
Here are the configure parameters I used to set up the build:
../gcc-10.2.0/configure --prefix=/opt/gcc-10.2.0 --build=$MACHTYPE --host=arm-linux-gnueabihf --target=arm-linux-gnueabihf --enable-languages=c,ada,c++,go,d,fortran,objc,obj-c++ --with-gcc-major-version-only --program-suffix=-10.2 --program-prefix=arm-linux-gnueabihf- --enable-shared --without-included-gettext --enable-threads=posix --enable-nls --enable-bootstrap --enable-clocale=gnu --enable-libstdcxx-debug --enable-libstdcxx-time=yes --with-default-libstdcxx-abi=new --enable-gnu-unique-object --disable-libitm --disable-libquadmath --disable-libquadmath-support --enable-plugin --with-system-zlib --with-target-system-zlib --enable-objc-gc=auto --enable-multiarch --disable-sjlj-exceptions --with-arch=armv6 --with-fpu=vfp --with-float=hard --disable-werror --enable-checking=release
