* include/private/gcconfig.h (GC_data_start): declare when needed.
* include/private/gc_priv.h: Include gcconfig.h after ptr_t
declaration.
* dyn_load.c (GC_register_dynamic_libraries_dl_iterate_phdr,
GC_register_dynlib_callback): Register main data for static
executable if dl_iterate_phdr() didn't.
* misc.c (GC_init_inner): Call GC_init_linux_data_start() even
if we don't expect to register main static data.
