GCC-4.7.2 installation on Cygwin fails

Because default GCC in Cygwin is 4.5.3, I tried to install GCC 4.7.2. I have dowloaded tar.bz archive from here, put it to cygwin\usr\gcc-4.7.2 and proceed the following sequence:

tar xvf gcc-4.7.2.tar.bz2
cd gcc-4.7.2
./contrib/download_prerequisites
mkdir build
cd build
../configure --build=x86_64-linux-gnu --prefix=/usr/gcc-4.7.2 --enable-checking=release --enable-languages=c,c++ --disable-multilib --program-suffix=-4.7
make
sudo ln -s /usr/lib/x86_64-linux-gnu /usr/lib64
sudo make install

I stucked at make with the following error: (after more than one hour)

make[3]: Leaving directory `/usr/gcc-4.7.2/build/gcc'

Does this log contain enoung information, to say what went wrong?

The full log is much more bigger so I allowed myself to put only the part of him. The instruction that I used, I found on Pastebin: http://pastebin.com/1MBaAikB

Could anyone give me a tip how could I solve this problem?

EDIT 1: I trieid to achieve it in annother way. I found an installation description on http://matpack.de/cygwin/index.html

tar -xf gcc-4.7.2.tar.bz2
mkdir gcc-build
cd gcc-build
../gcc-4.7.2/configure --enable-languages=c,c++
make -j 4
make install
make clean          (OPTIONAL)
cd ..

The error that I got, is connected now with 'permission denided'. Error log: http://pastebin.com/0stdpFKf

How this is possible?

I had come across the same problem. Just I have exported the library path of mpc, mpfr and gmp libraries to the LD_LIBRARY_PATH environment variable, then it is working.

GCC 4.7.2 is now available as a test release. In setup.exe, toggle the version numbers for all the gcc4-* packages, as well as libgcc1, libstdc++6, etc., until a 4.7 version is shown. Just keep in mind that you will have to elect to Keep each of these again during subsequent runs of setup.exe, until such time that they are declared stable.
