	FreeBSD).
	* dyn_load.c (GC_register_main_static_data): Move the definition
	above GC_register_dynamic_libraries_dl_iterate_phdr one (FreeBSD

	* dyn_load.c (GC_register_dynamic_libraries_dl_iterate_phdr): Test
	GC_register_main_static_data() result (instead of direct testing
	of dl_iterate_phdr (to prevent a compiler warning).
	* os_dep.c (CODE_OK): Test si_code also for the value of 2
	(FreeBSD case; required for FreeBSD v7+).
	* os_dep.c (CODE_OK): Properly use parentheses (HPUX case).
	* include/private/gcconfig.h (DATASTART): Cast etext argument in
	GC_FreeBSDGetDataStart() call; remove unnecessary "&" (FreeBSD
	case).
