Hi Tom,
this patch:
2006年08月21日 Bryce McKinlay <mckinlay@redhat.com>
 PR libgcj/13212:
 * configure.ac: Check for pthread_getattr_np(). Remove
 GC_PTHREAD_SYM_VERSION detection.
 * include/gc.h (GC_register_my_thread, GC_unregister_my_thread,
 GC_get_thread_stack_base): New declarations.
 * pthread_support.c (GC_register_my_thread, 
GC_unregister_my_thread,
 GC_get_thread_stack_base): New functions.
 (GC_delete_thread): Don't try to free the first_thread.
 * misc.c (GC_init_inner): Use GC_get_thread_stack_base() if 
possible.
 (pthread_create_, constr): Removed.
 (pthread_create): Don't rename.
 * include/gc_ext_config.h.in: Rebuilt.
 * include/gc_pthread_redirects.h (pthread_create): Define
 unconditionally.
 * include/gc_config.h.in: Rebuilt.
 * configure: Rebuilt.
Breaks build on libjava and tests in boehm-gc since 
GC_register_my_thread, GC_unregister_my_thread, GC_get_thread_stack_base 
are only implemented in pthread_support.c, they result in unresulved 
symbols when one links agains libgcjgc.so.
Solaris instead uses solaris_threads.c.
Now we have either to reduce this patch to only support pthreads or 
implement it for solaris_threads.c too.
