MinGW x64 dependencies missing

[rubenvb]

Using toolchains from MinGW-w64, one can build both x86 and x64 binaries for Windows using GCC.
Unfortunately, the required dependencies for 64-bit MinGW are missing, resulting in undefined reference errors (in the below case, to FreeType symbols):

If you need assistance in building the dependencies or installing a MinGW-w64 toolchain, I'll be very glad to help with that.

I am working on just this very issue actually. I've gotten libfreetype and libglew built with ruben's most recent win64 mingw64 release. The libjpeg from mingw64's sourceforge site seems to work as a 64-bit replacement.

Looking into libopenal and libsndfile now.

Looking into libopenal and libsndfile now.

There are already 64-bits versions of the libopenal and libsndfile DLLs in the SFML repository, so all you have to do is to regenerate the import libraries, there's no need to compile them.
