If the client (guile) creates several threads then it should define GC_THREADS on gc.h inclusion (so, if libgc is built as single-threaded, you will get a linkage error (GC_pthread_create or GC_register_my_thread is undefined)). Otherwise (if the client does not manipulate threads), single-threaded libgc should fit the client.

On Mac OS X, as far as I know, all libraries have been thread safe for years. So the expectation would be to build with threads enabled.

Is there a point building it without threads on such a platform?
