* configure.ac: Add stanza for *-*-gnu* threads configuration.
* configure: Regenerate.
* include/gc_config.h.in: Likewise.
* dyn_load.c (_GNU_SOURCE): Define for __GNU__.
* include/gc_config_macros.h (_REENTRANT, GC_PTHREADS): Define for
GC_GNU_THREADS.
* include/private/gcconfig.h (DATASTART): Don't define for I386 &&
HURD.
(SIG_SUSPEND, SIG_THR_RESTART, SEARCH_FOR_DATA_START): Define for
I386 && HURD.
(UNIX_LIKE, REGISTER_LIBRARIES_EARLY): Define for HURD.
* os_dep.c (GC_init_linux_data_start): Handle for HURD.
* pthread_support.c (GC_thr_init): Add case for GC_GNU_THREADS.
* specific.c: Use for GC_GNU_THREADS.
* threadlibs.c: Add case for GC_GNU_THREADS.
