	* allchblk.c (GC_freehblk): Print extended error message (done via
	GC_printf() before aborting with a short message) only if
	GC_print_stats.
	* dyn_load.c (GC_register_dynamic_libraries): Ditto.
	* os_dep.c (GC_get_maps, GC_register_data_segments, GC_remap,
	PROTECT, GC_write_fault_handler, GC_mprotect_thread): Ditto.
	* pthread_stop_world.c (GC_start_world): Ditto.
	* win32_threads.c (GC_register_my_thread_inner): Ditto.
	* os_dep.c (GC_get_main_stack_base, GC_register_data_segments,
	GC_dirty_init): Remove redundant print of an error message before
	aborting with the same message.
	* os_dep.c (GC_register_data_segments): Remove format specifier
	from the string passed to GC_err_puts(); use ABORT instead of EXIT
	(if invalid executable type).
	* os_dep.c (GC_remap): Adjust printf format specifier (for long
	type).
	* os_dep.c (GC_dirty_init): Print a message about SIG_IGN detected
	(for SIGSEGV/BUS) only if GC_print_stats.
	* os_dep.c (catch_exception_raise): Join 2 adjucent GC_err_printf
	calls.
