commit 653ccd78fa6770c692f5a737ad70de5aedbfcc7f
Author: Michael Gran <address@hidden>

    don't GC unregister null thread
    GC_unregister_my_thread is only supposed to be called from
    a thread other than the main thread, so, it should never be
    called when the system is compiled with null threads.
    * libguile/threads.c (on_thread_exit)[SCM_USE_NULL_THREADS]: don't
        call GC_unregister_my_thread

    check for GC_allow_register_threads
    This is not present in earlier versions of BDW-GC
    * check for GC_allow_register_threads
    * libguile/threads.c (scm_i_init_thread_for_guile): Only call
      GC_allow_register_threads if it is present.
