+/*
+Implements the atomic operations. For now TCC does not support
+the atomic versions on nix so it uses locks to simulate the same behavor.
+On windows tcc can simulate with other atomic operations.
+
+The @VEXEROOT/thirdparty/stdatomic contains compability header files
+for stdatomic that supports both nix, windows and c++.
+
+This implementations should be regarded as alpha stage and be
+further tested.
