97fcf583b7 jumps encoded using 24 bits, not 19; blocks no longer aligned
* libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bump.

  aligned; instead, jumps are encoded into 3 bytes instead of 2.
  (br, br-if, br-if-not, br-if-eq, br-if-not-eq, br-if-null)
  (br-if-not-null, mv-call): Adapt for new length of br instructions (3
  bytes instead of 2).

b0fae4ecaa bitvector tweaks
* libguile/arrays.c (scm_from_contiguous_typed_array):
* libguile/bytevectors.c (scm_uniform_array_to_bytevector): Error if the
  uniform element size is more than 8 bits, but not divisible by 8 --
  because our math could overflow in that case.

* module/ice-9/deprecated.scm (#\y): Indeed, #* is the valid bitvector
  syntax :)

31ab99de56 Restore signature of `scm_primitive_load_path ()' as found in 1.8.
The incompatibility was introduced by
0fb81f95b0 ("add exception_on_error
optional arg to primitive-load-path").

* libguile/load.c (scm_primitive_load_path): Change to take 1 rest
  argument.  Interpret the argument as either a file name (C-level
  backward compatibility with 1.8) or an actual argument list.
  (scm_c_primitive_load_path): Update caller.

* libguile/load.h (scm_primitive_load_path): Update accordingly.

* doc/ref/api-evaluation.texi (Loading): Update documentation of

28af5ee5ec add $libir to the ltdl path, not $pkglibdir; add extensionsdir
* libguile/Makefile.am (libpath.h): Fix SCM_LIB_DIR to point to the
  libdir, not pkglibdir. Add SCM_EXTENSIONS_DIR, for a dir to put in the
  dynamic-link search path that's not managed by ldconfig or the like;
  and put this dir in the "extensionsdir" key of %guile-build-info.

* libguile/dynl.c (sysdep_dynl_init): Rename the installed-libdir
  environment var to GUILE_SYSTEM_EXTENSIONS_PATH (from
  GUILE_SYSTEM_LTDL_PATH). Also add SCM_EXTENSIONS_DIR to the ltdl
  search path in the default case.

* meta/guile-2.0.pc.in: Add extensionsdir, so you can pkg-config
  --variable=extensionsdir guile-2.0.

03d80c0327 Revert changes that gather thread-specific local language
The method used was not portable.  However, the underlying problem
still exists: the uc_locale_language used by libunistring does not
work with thread-specific locale_t locales.

* libguile/i18n.c (locale_language): avoid unpacking semi-opaque type
  locale_t.

* test-suite/tests/i18n.test: set Turkish string and char locale upcase
  and downcase tests to throw untested

3d1af79fec Adjust to match changes in libgc's CVS (pre-7.2).
In libgc CVS the `GC_do_blocking ()' declaration is now public but it
uses a slightly different signature for its first argument.

* configure.ac: Check for `GC_fn_type'.

* libguile/threads.c (GC_fn_type)[HAVE_GC_DO_BLOCKING &&
  !HAVE_GC_FN_TYPE]: New typedef.
  (scm_without_guile): Explicitly cast `without_guile_trampoline' to
  `GC_fn_type'.  This is because the upstream definition currently
  looks like `typedef void * (extern *GC_fn_type)(void *);', which
  isn't compatible.

87f30eda98 Fix spurious `throw from within critical section' errors
The crux of this problem was that the thread doing a throw, and so
checking scm_i_critical_section_level, was different from the thread
that was in a critical section.

* libguile/async.h (scm_i_critical_section_level): Removed, replaced
  by per-thread critical_section_level.
  (SCM_CRITICAL_SECTION_START, SCM_CRITICAL_SECTION_END): Use
  per-thread critical_section_level.

aafb5062b8 Language-specific case-conversion doesn't honor locale
Libunistring uses a function uc_locale_language to extract the
current language from the locale information.  It does this by calling
setlocale.  This makes incompatible with Guile functions that use the
locale_t thread-specific locale API, because the values returned by the
call to setlocale ignore the locale set by uselocale.

As a workaround, this patch extracts the language from the locale_t
structure's __names field.

A more complete solution is needed.  Perhaps that solution would test
that the __names field exists in the configure step and revert to
!USE_GNU_LOCALE_API in that case.

* libguile/i18n.c (locale_language): new function that performs the
  same job as uc_locale_language but is compatible with uselocale
  (u32_locale_casecoll, u32_locale_tocase): replace uc_locale_language

5b87844575 Adapt i18n string and char comparison funcs for Unicode
* libguile/i18n.c (RUN_IN_LOCALE_SECTION) [USE_GNU_LOCALE_API]: new
  macro for this define.  Should work the same as the !USE_GNU_LOCAL_API
  version
  (SCM_STRING_TO_U32_BUF, SCM_U32_BUF_FREE): helper macros
  (compare_u32_strings, compare_u32_strings_ci): new functions that
  compare scheme strings in the presence of the locale
  (u32_locale_casecoll): new helper function for compare_u32_strings_ci
  (compare_strings, compare_strings_ci): removed and replaced by
  compare_u32_strings and compare_u32_strings_ci
  (scm_string_locale_lt, scm_string_locale_gt, scm_string_locale_ci_lt)
  (scm_string_locale_ci_gt, scm_string_locale_ci_eq): modified to
  use new compare_u32_strings and compare_u32_strings_ci comparison
  functions
  (scm_char_locale_lt, scm_char_locale_gt, scm_char_locale_ci_lt)
  (scm_char_locale_ci_gt, scm_char_locale_ci_eq): modified to use
  new compare_u32_strings and compare_u32_strings_ci comparison
  functions

ba20f78a6c Fix omission of VM frames from backtrace
From the time when a #<program> was a SMOB, really_make_boot_program
in vm.c was still using SCM_SET_SMOB_FLAGS to set the
SCM_F_PROGRAM_IS_BOOT flag - which meant that it was setting flag
1<<32 :-) which obviously was then missed by the SCM_PROGRAM_IS_BOOT
calls in stacks.c.

* libguile/programs.h (SCM_F_PROGRAM_IS_BOOT): Use a less significant
  bit for this flag, now that programs use a tc7 type.

* libguile/vm.c (really_make_boot_program): Don't use
  SCM_SET_SMOB_FLAGS, now that programs aren't SMOBs.

931c82f5b0 Fix incorrect stack count warnings
* libguile/stacks.c (stack_depth): Decrement depth count for a
  macro-expansion frame.  (Missing this decrement will cause a "stack
  count incorrect" warning but is actually benign, as it only means
  that scm_make_stack allocates a bit more space for the stack than it
  really needs.)

  (read_frames): Increment count of remaining unused frames, when
  cutting out a macro transformer application frame.  (Missing this
  increment could cause the "stack count incorrect" warning, and could
  make read_frames think it's filled up all the available stack frames
  when there's actually still one frame unused; this wasn't benign,
  because it could cause information to be missing from a stack
  trace.)

a29c00447b Remove unhittable else branch for nonexistent type of debug frame
* libguile/stacks.c (stack_depth): Remove unhittable else branch
  apparently catering to a kind of frame that isn't an eval, apply or
  void frame - in fact there are no other kinds of frames.

eb350124a8 add the libdir to the ltdl lib search path
* libguile/Makefile.am (libpath.h): Fix pkgdatadir, pkglibdir, and
  pkgincludedir entries. Add a new define, SCM_LIB_DIR.

* libguile/dynl.c (sysdep_dynl_init): Add the libdir to the libltdl
  search path. Should fix
  http://thread.gmane.org/gmane.lisp.guile.bugs/4289/focus=4296 -- that
  is, it should allow guile to be invoked from whereever it is
  installed, without munging LTDL_LIBRARY_PATH or the like variables.

  There is a trick though -- during the build, we don't want to be
  looking in the $libdir for loadable modules. So as with
  GUILE_SYSTEM_PATH, we have GUILE_SYSTEM_LTDL_PATH.

* meta/uninstalled-env.in: Set GUILE_SYSTEM_LTDL_PATH to "" when
  building.
