0083cb5ec4 fix self tail recursion to different case-lambda clauses
http://savannah.gnu.org/bugs/?33362

* module/language/tree-il/compile-glil.scm (flatten-lambda-case): Rename
  from flatten, as it really just takes a particular case.  Instead of
  iteratively compiling lambda cases through `comp', tail-call through
  flatten-lambda-case.  This allows code to see which case it's being
  compiled in.  Take advantage of that to limit the self-tail-call
  optimization to self-calls to the same case -- otherwise we might be
  jumping to a label without having reserved the right number of
  locals.
  (flatten-lambda): Adapt the caller.

* test-suite/tests/compiler.test ("case-lambda"): Add a test.

* acinclude.m4 (gl_CLOCK_TIME): It could be that clock_gettime is in
  libc but clock_getcpuclockid is not, so check for that explicitly.

* libguile/strings.c (scm_i_allocate_string_pointers): Encode strings
  using the current locale.  Previously, Latin-1 was used.  Indirectly,
  this affects the encoding of strings in `system*', `execl', `execlp',
  `execle', `environ', and `dynamic-args-call'.

  (scm_makfromstrs): In header comment, clarify that the C strings are
  interpreted according to the current locale encoding.

to a separate script

* meta/guile-tools.in: Use (ice-9 getopt-long).

  (directory-files, strip-extensions, unique, find-submodules,
  list-scripts): Deleted (and moved to new `list.scm' file).

  (getopt): Deleted.

  script is specified.

6b4b4bfb09 Implement #:stop-at-first-non-option option for getopt-long
(For use by guile-tools)

* module/ice-9/getopt-long.scm: Use (ice-9 optargs) so we can use
  define*.

  (process-options): Add stop-at-first-non-option parameter.  When
  this is true, stop processing when we hit a non-option (so long as
  that non-option isn't something that resulted from the unclumping of
  a short option group).

  (getopt-long): Add #:stop-at-first-non-option keyword; pass it on to
  process-options.

* test-suite/tests/getopt-long.test ("stop-at-first-non-option"): New
  test (for the above).

0faf4b2a74 Handle short option unclumping progressively, instead of all upfront
This is needed as a prerequisite for the following change that
introduces the stop-at-first-non-option option, because when that
option is used we don't know upfront how far through the command
line we should proceed with unclumping.

* module/ice-9/getopt-long.scm (expand-clumped-singles): Delete.

  (process-options): Add a loop variable to indicate how many elements
  at the start of `argument-ls' are known not to be clumped.  When we
  see a short option and this variable is <= 0, perform unclumping
  (using code that used to be in expand-clumped-singles) and loop with
  the variable > 0.

  (getopt-long): Don't call expand-clumped-singles upfront here.

1e2cc0b630 Simplify getopt-long handling of option values, esp with multiple occurrences
Basically, accumulate values in the `process-options' loop variables,
instead of using set-option-spec-value!

* module/ice-9/getopt-long.scm (option-spec): Delete the `value' slot.

  (process-options): Delete `val!loop' and just use `loop' everywhere
  instead.  When adding an option spec to `found', add the
  corresponding value too; hence `found' becomes an alist, where it
  was previously a list of specs.

  (getopt-long): Use assq-ref to get values out of `found'.  Remove
  unhittable error condition for detecting an option that requires an
  explicit value, where a value wasn't supplied.  This condition is
  actually caught and handled in `process-options'.  Rewrite the end
  of the procedure much more simply.

  (scm_i_has_source_properties): New helpers.
  (scm_source_whash): Make static.

* libguile/read.c (scm_read_sexp): Remove register declarations here;
  let's trust the compiler.  Remove code to incrementally build up a
  copy; instead let's let scm_i_set_source_properties_x handle copying
  the expression if needed.
  (scm_read_quote, scm_read_syntax): Use scm_i_set_source_properties_x.
  (recsexpr): Remove this helper from 1996.
  (scm_read_sharp_extension): Instead of trying to recursively label
  sharp-read subforms with source properties, just label the outside
  form and rely on the macro-expander to propagate it down.

2a3db25e28 Don't call scm_lock_mutex and scm_unlock_mutex via pointer of wrong type
* libguile/threads.c (lock_mutex_return_void, unlock_mutex_return_void):
  New static functions that simply call scm_lock_mutex and
  scm_unlock_mutex, respectively, but return void instead of SCM.

  (scm_dynwind_lock_mutex): Pass unlock_mutex_return_void to
  scm_dynwind_unwind_handler_with_scm, and lock_mutex_return_void to
  scm_dynwind_rewind_handler_with_scm.  Previously, we passed
  scm_unlock_mutex and scm_lock_mutex (which return SCM), but the
  scm_dynwind_* functions expect pointers to functions which return
  void.  When SCM is of type union, this changes the calling conventions
  of the functions on some platforms (e.g. GCC 4.5.2 and 4.5.3 on x86).
