I downloaded the GCC 4.7.1 source and unpacked it, inside the gcc source directory I placed the folders mpc,mpfr and gmp containing the latest sources of the libraries. As I am told, GCC should automatically find,compile and statically link against them. I also created a folder called 'gcc-obj' inside the gcc source folder and from withing it I called the following configure command: ../configure --enable-languages=c,c++ --disable-sjlj-exceptions --enable-libgcj --enable-libgomp --with-dwarf2 --disable-win32-registry --enable-libstdcxx-debug --enable-concept-checks --enable-version-specific-runtime-libs --prefix=/c/gcc-obj --with-gmp=gmp --with-mpfr=mpfr --with-mpc=mpc I included the --with-mpc,mpfr and gmp switches to be on the safe side. After the configure finishes, I call 'make -j4' to build faster. Around 10-15 minutes later I get the following error checking for i686-pc-mingw32-gcc...
