* libguile/bytevectors.h: * libguile/bytevectors.c (scm_c_take_gc_bytevector): Rename this internal function, from scm_c_take_bytevector. This indicates that unlike the other scm_take_* functions, this one takes GC-managed memory. * libguile/objcodes.c (scm_objcode_to_bytecode): * libguile/vm.c (really_make_boot_program): Use scm_gc_malloc_pointerless, not scm_malloc. Thanks to Stefan Israelsson Tampe! * libguile/r6rs-ports.c: * libguile/strings.c: Adapt to renames.
