* module/language/tree-il/compile-glil.scm (flatten-lambda): Don't emit
a self-label, because when we can't match the args for a lexical call,
we have no space to shuffle args and jump.
(flatten): Apply the self-tail-call optimization to optional args
too, but only if the procedure is fix-allocated. If we can't apply the
optimization, use the normal tail-call sequence.

scm_current_processor_count): New functions.

fluid, rather than requiring that its value be `void'.

Use #{`}#, #{,}# and #{,@}# as the quasiquote, unquote and
unquote-splicing operators, respectively. Previously they were named
escaping.
* module/language/elisp/compile-tree-il.scm (unquote?): Change "\," to
"#{,}#".
(unquote-splicing): Change "\,@" to "#{,@}#".
(#{compile-`}#): Rename from #{compile-\`}#.

* libguile/fluids.c (scm_make_undefined_fluid, scm_fluid_unset_x)
(scm_fluid_bound_p): New functions.
(fluid_ref): New function; like scm_fluid_ref, but will not throw an
error for unbound fluids.
(scm_fluid_ref, swap_fluid): Use `fluid_ref'.
* libguile/fluids.h (scm_make_undefined_fluid, scm_fluid_unset_x)
(scm_fluid_bound_p): New prototypes.
* libguile/vm-i-system.c (fluid_ref): If fluid is unbound, jump to
`vm_error_unbound_fluid'.
* libguile/vm-engine.c (VM_NAME)[vm_error_unbound_fluid]: New error
message.
* test-suite/tests/fluids.test ("unbound fluids")["fluid-ref of unbound
fluid", "fluid-bound? of bound fluid", "fluid-bound? of unbound
fluid", "unbound fluids can be set", "bound fluids can be unset"]: New
tests.
* test-suite/guile-test: Use "../meta/guile" as the interpreter instead
of "../libguile/guile".
(default-test-suite): New function, replacing the variable of the same
name. Look for tests in the same directory as the guile-test script.
Throw an error if not invoked as `guile-test'.
(test-suite): The old default value of `default-test-suite' could now
throw an error, and this already gets initialized in `main', so don't
provide an initial value.
* module/web/http.scm: Add commentary.
(parse-quality): Allow .NNN to be interpreted as 0.NNN.
* test-suite/tests/web-http.test ("request headers"): Add a test.

(assertion-violation): Properly treat a #f `who' argument.
* module/rnrs/conditions.scm (condition): Use `assertion-violation'
instead of the undefined `raise'.
(define-condition-type): Fix for multiple fields.
* test-suite/tests/r6rs-conditions.test: Test accessors of a
multiple-field condition. Also import `(rnrs base)' to allow
stand-alone running of the tests; apparently the `@' references
scattered throughout the R6RS modules make the libraries sensitive to
their load order -- for instance, trying to load `(rnrs conditions)'
before `(rnrs base)' is loaded fails.
* module/rnrs/records/inspection.scm: Use `assertion-violation' instead
of an explicit `raise'.
* module/rnrs/records/syntactic.scm (process-fields): Use
`syntax-violation' instead of bogus invocations of `error'.
* libguile/regex-posix.c (fixup_multibyte_match): Fixup the match

* module/rnrs/enums.scm (enum-set-union, enum-set-intersection,
enum-set-difference): Compare enum-set universes with `equal?' to support
sets generated using constructor syntax bound by `define-enumeration'.

* libguile/r6rs-ports.c (make_bip, make_cbip, make_bop, make_cbop): Lock
the port table.
* libguile/r6rs-ports.c (make_bop): Let the returned extraction
procedure refer to the port's buffer instead of the port itself. This
fixes a segfault if the port is closed before the extraction procedure
is called.
(bop_proc_apply): Adapt accordingly.
* test-suite/tests/r6rs-ports.test (8.2.10 Output ports): Add testcase
for extraction after close.

form of syntax errors. Adapt all tests.

* libguile/numbers.c (scm_iuint2str): Add an assertion on the domain of
the radix. Use the number_chars table to write the string, instead of
doing strange math. Same effect, though.
(mem2uinteger, char_decimal_value): Change logic to allow all ascii
alphabetic chars as decimals, not just a-f. Thanks to Nils Gey for the
report.
* test-suite/tests/numbers.test ("number->string"): Add some tests.
* module/web/http.scm (parse-media-type, validate-media-type,
(content-type): Change to represent media types as ("foo/bar" ("param"

(validate-uri, uri-decode, uri-encode): Use uri-error.
* test-suite/tests/web-uri.test: Update for uri-error.
* module/srfi/srfi-38.scm: New file, partly based on the reference
implementation and on Alex Shinn's public-domain implementation for
Chicken.
