Building GCC 9.3 meet some error

[Efreets]

Hi,
Do you have some time to help me to solve the problem with building gcc 9.3 on windows?
Thanks.

Here was my information during Build gcc, how it makes, I'm my best to solve the error, but it's no work

My configure is

../gcc-9.3.0/configure --host=x86_64-w64-mingw32 --build=x86_64-w64-mingw32 --target=x86_64-w64-mingw32 --prefix=/P/Efreets/gcc930/ --with-sysroot=/P/Efreets/gcc930/ --enable-languages=c,lto,c++,fortran --enable-lto --enable-static --disable-symvers --disable-shared --enable-threads=posix --enable-sjlj-exceptions --with-system-zlib --with-gmp=/P/Efreets/gmp620 --with-mpfr=/P/Efreets/mpfr402 --with-mpc=/P/Efreets/mpc110 --with-isl=/P/Efreets/isl221 --with-zstd=/P/Efreets/zstd144

It's meet this error
