scm_c_define_gsubr_with_generic): New functions. They replace
scm_make_gsubr and scm_make_gsubr_with_generic. The `make' variants
only create the gsubr object, while the `define' variants also put it
into the current module. Changed all callers. (scm_make_gsubr,
scm_make_gsubr_with_generic): Deprecated.
(scm_c_make_subr, scm_c_define_subr, scm_c_make_subr_with_generic,
scm_c_define_subr_with_generic): New functions. They replace
scm_make_subr, scm_make_subr_opt and scm_make_subr_with_generic. The
`make' variants only create the subr object, while the `define'
variants also put it into the current module. Changed all callers.
(scm_make_subr, scm_make_subr_opt, scm_make_subr_with_generic):
Deprecated.
eval.c can use it.
(scm_call_with_values): Removed.
* values.c (values_vtable, scm_values_vtable): Added "scm_" prefix
so that it can be exported.
(scm_call_with_values): Removed.
* values.c, values.h: new files. use a struct to contain multiple
values, similar to the previous Scheme-level implementation.
* Makefile.am: add values.c, values.h, values.x.
* continuations.c (continuation_apply): support R5RS multiple value
continuations.
* init.c: call scm_init_values.
* struct.h: define SCM_SET_STRUCT_PRINTER.
