	* misc.c (GC_init): Use HOTTER_THAN (instead of STACK_GROWS_DOWN)
	for GC_stackbottom assertion.
	* os_dep.c (GC_enclosing_mapping): Define only if IA64 or
	INCLUDE_LINUX_THREAD_DESCR; make GC_INNER.
	* pthread_support.c (GC_enclosing_mapping): Declare (only if
	INCLUDE_LINUX_THREAD_DESCR).
	* os_dep.c (GC_get_main_stack_base): Don't call pthread_getattr_np
	if REDIRECT_MALLOC as the former is observed to call redirected
	malloc (while GC is not initialized yet) on some Linux platforms.
	* include/private/gc_priv.h (MAX_HEAP_SECTS): Don't use a smaller
	value for SMALL_CONFIG if USE_PROC_FOR_LIBRARIES defined.
