In this setup you must not call GC_INIT() but instead only 
GC_use_DllMain().  The reason is that GC_INIT() registers the main 
thread (which is good) but uses the wrong method since 
GC_win32_dll_threads still is 0 (which is bad).  Since GC_use_DllMain() 
now calls GC_init_parallel() (now with GC_win32_dll_threads set to 1) 
which in turn finally calls GC_INIT() there is no need to call GC_INIT() 
explicitly anyway.
