* libguile/bitvectors-internal.h: New file. * libguile/Makefile.am (noinst_HEADERS): Add new file. * libguile/bitvectors.c: Adapt to add scm_ prefix to the is_bytevector, bytevector_bits, etc helpers. * libguile/bitvectors.h (scm_is_bitvector): Define inline. Remove internal defines from the header. * libguile/eq.c: * libguile/init.c: * libguile/print.c: * libguile/array-handle.c: Adapt.
