4 tests failed on gmp 5.0.3 using mingw64 gcc 4.7

[Rene Sugar]

I got the following 4 errors on gmp 5.0.3 when running "make check" on a 
mingw64 build on Windows 7 64-bit.

./configure --host=x86_64-w64-mingw32 --build=x86_64-w64-mingw32 
--target=x86_64-w64-mingw32 --prefix=/mingw
make
make check

My CPU is an AMD Phenom II X4 940 processor. The configure script picked 
"k8" instead of "amdfam10".

Here is the build of gcc I used:

(mingw64 project also lets you cross-compile mingw32 and mingw64 builds 
on Linux)

mingw64 toolchain sources with build scripts to create cross-compilers:

http://sourceforge.net/projects/mingw-w64/files/Toolchain%20sources/Personal%20Builds/rubenvb/

mingw64 toolchain binaries:

http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/rubenvb/4.7.0-1/ 



This wiki page has a good explanation of how to set up mingw64 on Windows:
