        * boehm-gc/include/gc.h: (GC_CreateThread) This function is
          now exposed on all Win32 platforms.
        * boehm-gc/win32_threads.c: (GC_CreateThread) This now
          compiles on Win32; it invokes CreateThread() if GC is built
          as a DLL; otherwise it registers the thread.
        * boehm-gc/misc.c (GC_init): Initialize GC_allocate_ml in case
          libgcjgc was not built as a DLL.
