Unable to install latest GCC on Windows

I am trying to install GCC on my local system.

I am referring this

I have successfully completed the following steps:

1. Install Cygwin

2. Install Required Cygwin Packages

    C:\cygwin64>setup-x86_64.exe -q -P wget -P gcc-g++ -P make -P diffutils -P libmpfr-devel -P libgmp-devel -P libmpc-devel

3. Download, Build and Install the Latest GCC

   $ wget http://ftpmirror.gnu.org/gcc/gcc-9.2.0/gcc-9.2.0.tar.gz$ tar xf gcc-9.2.0.tar.gz$ mkdir build-gcc$ cd build-gcc

After this while configuring the gcc-9.2.0 using the below command I am facing the following error:

    $ ../gcc-9.2.0/configure --enable-languages=c,c++ --disable-bootstrap --disable-sharederror:    configure: creating ./config.status    ./config.status: line 470: syntax error near unexpected token `)'    ./config.status: line 470: `    *\'*) ac_optarg=`$as_echo "$ac_optarg" | sed "s/'/'\\\\\\\\''/g"` ;;'

Any solution for this or alternate website link for downloading latest gcc binaries for windows will be highly appreciated.
