* module/ice-9/psyntax.scm (include): Like `load', interpret relative
paths as being relative to the file that does the `include'.
* doc/ref/api-evaluation.texi: Update docs.
* doc/ref/libguile-concepts.texi (Multi-Threading): Use functions in the
example instead of macros. Performance is really not a concern with
this interface, especially now that scm_car and scm_cdr are inline
functions.
* doc/ref/api-smobs.texi (Smobs): Document scm_new_smob and
scm_new_double_smob instead of the SCM_NEWSMOB / SCM_RETURN_NEWSMOB
family of macros.
* doc/ref/libguile-smobs.texi (Creating Smob Instances): Use
scm_new_smob.
* libguile/vm-i-scheme.c (VM_VALIDATE_STRUCT): Fix the error message if
the value was not a struct.
* module/system/base/compile.scm (find-language-joint): Default to
joining at the target language.
(default-language-joiner): Allow sequences of one compiled expression
to pass through. Otherwise error as before.
(read-and-parse): New helper; actually parses.
(read-and-compile): Use read-and-parse, and fall back to
default-language-joiner.
Thanks to Nala Ginrut for the report.
* module/system/base/compile.scm (read-and-compile): Close the input
port after we read all of its data. Perhaps this cleans up some NFS
ghosts that David Pirotte was seeing.
* libguile/load.c (scm_primitive_load_path): If the second argument is a
procedure, call it like a thunk.
* doc/ref/api-evaluation.texi (Load Paths): Update docs.
* module/ice-9/boot-9.scm (resolve-interface): Use `unless'.
(try-module-autoload): Use the new primitive-load-path to detect
failure to find an appropriate file. Fixes a bug reported by Diogo
F. S. Ramos. Thanks to Noah Lavine for tracking it down.
* libguile/weak-table.c (GC_move_disappearing_link)
(move_disappearing_links): Factor out stub, as in previous weak-set
commit.
(resize_table): As in weak-set commit, finalizers do not run within
allocators.
(do_vacuum_weak_table): Add comment about need for trylock.
(scm_c_make_weak_table): Use the new scm_i_register_weak_gc_callback.
Previously this was the case because of a mistyped check for a
"HAVE_GC_TABLE_START_CALLBACK" symbol, whereas the symbol was actually
HAVE_GC_SET_START_CALLBACK. Anyway, it's better to call this after GC
anyway, as vacuuming might need to allocate weak links (on pre-7.3
libgc without GC_move_disappearing_link) or reallocate the backing
vector.
* libguile/finalizers.h:
* libguile/finalizers.c (scm_i_register_weak_gc_callback): New internal
helper, from weak-set.c.
Relative to the previous weak-set.c version, prefer the
finalizer-based implementation. Fix bug regarding confusion between
scm_before_gc_c_hook and scm_after_gc_hook. Fix bug regarding
referencing weak values outside of the alloc lock.
* libguile/weak-set.c (GC_move_disappearing_link): New stub.
GC_move_disappearing_link is only available in libgc 7.3.
(move_weak_entry): Use the new stub instead of ifdeffery.
(resize_set): Now that we run finalizers from a separate thread or
async, we can keep the lock while reallocating the set vector.
(do_vacuum_weak_set): For the same reason, always lock the set.
Remove implementation of scm_c_register_weak_gc_callback in preference
of the new copy in finalizers.c.
(scm_c_make_weak_set): Use the new scm_i_register_weak_gc_callback.
* libguile/gc.c: Remove shims for GC_get_heap_usage_safe,
GC_get_free_space_divisor, and GC_set_finalize_on_demand. Remove code
in the case in which we did not have GC_set_start_callback.

lib/jit_mips.c, lib/jit_note.c, lib/jit_ppc.c, lib/jit_print.c,
lib/jit_x86.c, lib/lightning.c: Extend the "jit_note" abstraction
with the new "jit_name" call, that receives a string argument, and
should usually be called to mark boundaries of functions of code
generating jit (that is, it is not expected that the language
generating jit map its functions to jit functions).

include/lightning/jit_mips.h, include/lightning/jit_ppc.h,
include/lightning/jit_private.h, include/lightning/jit_x86.h:
Make JIT_RET, JIT_FRET and JIT_SP private. These should not be
used in any operations due to frequently having special
constraints (usually JIT_FRET). JIT_FP must be made available
because it must be used as the base register to access stack
space allocated with jit_allocai.
* libguile/posix.c (scm_fork): Issue a warning on a multithreaded fork.
* doc/ref/posix.texi (Processes): Add note about multithreaded fork.
* test-suite/tests/00-socket.test: Moved here, from socket.test, so as
to run before any threads are created.
* test-suite/Makefile.am: Adapt.
* libguile/posix.c (scm_fork): Issue a warning instead of an error on a
multithreaded fork.
* doc/ref/posix.texi (Processes): Add note about multithreaded fork.
* module/system/vm/trace.scm (build-prefix): New helper.
(print-application, print-return): Use the helper.
(trace-calls-to-procedure, trace-calls-in-procedure):
(trace-instructions-in-procedure, call-with-trace): Add #:max-indent
argument, defaulting to the terminal width less 40 characters.
* doc/ref/scheme-using.texi: Update `trace' docs.
Based on a patch by Nala Ginrut.
* module/language/tree-il/peval.scm (peval): Gensyms use whitespace as
an infix, not a dash. Helps gensym?-like procedures like those in the
unused lexical analysis.

module/ice-9/peg/string-peg.scm: update S-expression generators to use the
new *, +, ?, followed-by, and not-followed-by forms.
module/ice-9/peg/codegen.scm: remove the 'body' form in the PEG s-expression
representation.
* module/ice-9/peg.scm: move code out of here
* module/ice-9/peg/match-records.scm: remove this file
* module/ice-9/peg/using-parsers.scm: make a new module with utilities for
using parsers. It contains the code from both peg.scm and match-records.scm
* module/ice-9/peg/string-peg.scm: update to use new module
* module/ice-9/peg/codegen.scm: Make the PEG syntax extensible, and
move most of the current code generators to the new interface
* doc/ref/api-peg.texi: Document PEG extensions in the PEG Internals
section of the manual
* module/ice-9/peg/codegen.scm: peg-sexp-compile no longer knows about
string PEGs
* module/ice-9/peg.scm: add a new function peg-extended-compile that
calls peg-sexp-compile or peg-string-compile on its argument as
appropriate
* module/ice-9/peg/string-peg.scm: remove define-nonterm and make a simpler
macro called `define-sexp-parser' to make the PEG grammar
* module/ice-9/peg.scm: move define-nonterm macro to this file
* module/ice-9/peg/codegen.scm: move code to wrap a parser result nicely to
this file, under name `wrap-parser-for-users'
