* libguile/gc.c (scm_object_address): use uintptr_t instead of ulong
* libguile/gen-scmconfig.c (main): handle different sizes of scm_off_t
* libguile/integers.c (scm_integer_length_z): the mask size is bitcnt_max,
not UINTPTR_MAX
* libguile/ports.c (scm_set_port_line_x): test that line is an intptr_t,
not a long
* libguile/srfi-60.c (scm_srfi60_rotate_bit_fields): use correct size of
integer for bit-shifting
(scm_srfi60_reverse_bit_field): use correct integer size for bit-shifting
* libguile/symbols.h (scm_i_symbol_hash): cast to uintptr_t, not unsigned long
