linker error on MinGW build

[Philipp Kraus]

Hello,

I try to build OpenAL under MinGW and get the linker errors:

Linking C shared library OpenAL32.dll

I get the source from the Git repo and run cmake to create MinGW Makefile, after that I run mingw32-make and get the linker error.
How can I fix the build?

Thanks

Phil

Those are GCC atomic intrinsics, so it's a bit strange to see them in a
linker error. What version of GCC are you using in mingw? (What build of
mingw are you using? I'm pretty sure I cross-compile continuously with mxe)

I use gcc 4.7.1, I'm testing the mach flag :-)
