Hi Robert, A rather crude implementation could look something like this.

My limited benchmarks did not show any performance differences. But in the current form the code will result in compiler errors, due to the fact that both _OPENTHREADS_ATOMIC_USE_GCC_BUILTINS and _OPENTHREADS_ATOMIC_USE_WIN32_INTERLOCKED are defined. A simple solution would be to modify the CMake script so that these two cannot be defined simultaneously. And as you previously suggested to select the GCC-path when compiling with GCC under MinGW. Could you have a bash at this? Robert.
