* libguile/strports.c (scm_mkstrport): Use UTF-8; ignore

(SRFI-6): Remove text that mentions non-compliant behavior of
core string ports.
* module/ice-9/format.scm (format):
* module/ice-9/pretty-print.scm (truncated-print):

'set-port-encoding!' to set the string port encoding.
(%utf8/ascii-port, %utf8/wide-port, "rdelim"): Don't set
%default-port-encoding before creating string ports.
* test-suite/tests/r6rs-ports.test ("lookahead-u8 non-ASCII"): Don't set
%default-port-encoding before creating string ports.
("put-bytevector with UTF-16 string port", "put-bytevector with

the string port encoding.
("truncated-print"): Use 'pass-if-equal'.
* test-suite/tests/ports.test ("encoding failure leads to exception",
"%default-port-encoding is honored", "peek-char [latin-1]", "peek-char
[utf-8]", "peek-char [utf-16]"): Remove tests.

"wrong encoding, error", "wrong encoding, substitute",
"wrong encoding, escape"): Use 'set-port-encoding!' to set the
string port encoding.
("%default-port-encoding, wrong encoding"): Rewrite to use
a file port instead of a string port.
* libguile/vm-engine.c (INUM_MIN, INUM_MAX): Redefine without making
assumptions about the representation.

(idbl2str, scm_max, scm_min, scm_angle, log_of_shifted_double,
scm_log10): Use 'copysign' to check signs of zeroes,
instead of 'double_is_non_negative_zero'.

operands before adding, to avoid overflow when the result is the most
positive fixnum.
* libguile/struct.h:
* libguile/struct.c (scm_allocate_struct): New interface: allocates a
struct.
* libguile/vm-engine.c (allocate_struct): Instead of make-struct with a
rest arg, separate allocation from initialization.

call, and expect the caller to arrange the proc and arguments.
* test-suite/tests/rtl.test ("call"): Update tests.
* libguile/vm-engine.c: Change the RTL VM to number the procedure as
local 0, and other locals from 1. In the future we will want the FP
to point to local 0 instead of local 1. In the future also we can
elide the procedure for well-known closures (closures in which all
references are known call sites).
(make_closure, free_set): Instead of taking rest arguments, we add a
new free-set! op that initializes closures.
(free_ref): Take the closure as an argument.
* libguile/vm.c (rtl_boot_continuation_code): Remove comments, which

Whoops!
Fixes <http://bugs.gnu.org/14905>.
Reported by Göran Weinholt <goran@weinholt.se>.

* libguile/numbers.c (scm_num_eq_p): Fix bug comparing fractions to
infinities (reported by Göran Weinholt <goran@weinholt.se>). Fix

Use similar logic for inum/complex comparison to avoid rounding

New macro.
(scm_i_divide2double): Use INUM_LOSSLESSLY_CONVERTIBLE_TO_DOUBLE to
determine if our fast path is safe. Previously, negative arguments
were not checked properly.

Fixes <http://bugs.gnu.org/14864>.
Reported by Göran Weinholt <goran@weinholt.se>.
* libguile/vm-i-scheme.c (ash): Fallback to 'scm_ash' for right shifts
with counts >= SCM_I_FIXNUM_BIT, since '>>' is not guaranteed to work
correctly for large counts.

with-fluids.
* libguile/dynstack.c (scm_dynstack_push_fluid):

fluid binding.

change.
* libguile/vm-engine.c (rtl_vm_engine): Change wind-fluids / unwind-fluids

* libguile/vm-i-system.c (push-fluid, pop-fluid):
* doc/ref/vm.texi (Dynamic Environment Instructions): Rename wind-fluids
to push-fluid, and unwind-fluids to pop-fluid. They now only work on
one fluid binding at a time.
* module/ice-9/boot-9.scm (with-fluid*): Implement in Scheme in terms of
primcalls to push-fluid and pop-fluid.
(custom-throw-handler, catch, with-throw-handler): Use with-fluid*
instead of with-fluids, as with-fluids is no longer available before
psyntax is loaded.
(with-fluids): Define in Scheme in terms of with-fluid*.
* libguile/fluids.c (scm_with_fluid): Rename from scm_with_fluids, and
don't expose to Scheme.

primcalls to push-fluid and pop-fluid in compile-glil.scm and
effects.scm.
* module/language/tree-il/peval.scm (peval): Factor out
with-temporaries; probably a bad idea, but works for now. Factor out

* libguile/expand.c: Remove scm_sym_at_dynamic_wind.
* libguile/memoize.c (do_wind, do_unwind): A couple of hacky subrs. If
we see a wind or unwind primcall, we expand to a call of a quoted subr
value. It works and removes a kind of memoized value from the
interpreter. For the compiler,primcalls to wind and unwind are
handled specially.
(MAKMEMO_DYNWIND): Remove.
(scm_tc16_memoizer): Remove. Yay!
(memoize): Remove speculative lookup for toplevels to see if they are

call-with-values primcall, without the @, and fall back to a normal
call.

call-with-values.
* module/language/tree-il/primitives.scm (*interesting-primitive-names*):
(*multiply-valued-primitives*): Remove @call-with-values.
* libguile/memoize.c (memoize): Recognize a primcall to 'apply as
SCM_M_APPLY.
(@apply): Remove @apply memoizer.
(unmemoize): Unmemoize using "apply", not "@apply".
* libguile/memoize.h:
* libguile/expand.c (scm_sym_atapply): Remove.
* module/ice-9/boot-9.scm (apply): Re-implement using apply primcall.
Use case-lambda, so as to give an appropriate minimum arity.
* module/language/tree-il/compile-glil.scm (flatten-lambda-case):
Compile a primcall of "apply" specially, not "@apply".
* module/language/tree-il/peval.scm (peval): Match primcalls to "apply",
not "@apply". Residualize "apply" primcalls.
* module/language/tree-il/primitives.scm (*interesting-primitive-names*):
(*multiply-valued-primitives*): Remove @apply, and apply primitive
expander.
* test-suite/tests/peval.test:
* test-suite/tests/tree-il.test: Update tests to expect residualized
"apply".

better apply arity.
