* configure.in: Use `AC_CONFIG_MACRO_DIR([m4])'. Reverts patch
b01284227e and makes `libtoolize' from
Libtool 2 happier (removes a couple of warnings).
* Makefile.am (ACLOCAL_AMFLAGS): Remove `-I guile-config' since that
directory only contains macros that we distribute, not macros that we
use.
For explanation, see comments and text in the new file
libguile/measure-hwm.scm.
* .gitignore: Add libguile/stack-limit-calibration.scm.
* check-guile.in: Load libguile/stack-limit-calibration.scm.
* configure.in: Add AC_CONFIG_FILES to generate test-use-srfi from
test-use-srfi.in.
* libguile/Makefile.am (TESTS, TESTS_ENVIRONMENT,
stack-limit-calibration.scm): New targets, so that `make check'
calibrates the stack limit before running the Guile test suite.
* libguile/measure-hwm.scm: New file, calibrates stack limit for `make
check'.
* libguile/stackchk.c (scm_sys_get_stack_size): New primitive.
* libguile/stackchk.h (scm_sys_get_stack_size): New primitive
(declaration).
* test-suite/standalone/test-use-srfi: Renamed test-use-srfi.in, so
that ./configure can fill in variables in it.
* test-suite/standalone/test-use-srfi.in: Load
libguile/stack-limit-calibration.scm.
* configure.in: Update stack direction test to be like that in
Autoconf _AC_LIBOBJ_ALLOCA and Gnulib; specifically in involving a
function calling itself.
* debugger/commands.scm (evaluate, info-args, info-frame,
position, up, down): Improve/fix doc strings.
* Makefile.am (SUBDIRS): Add debugging.
(ice9_sources): Add gds-client.scm and gds-server.scm.
* scheme-debugging.texi: Remove lots of text that is now
duplicated (exactly) elsewhere, leaving only the `Tracing' node.
* guile.texi: Replace `Debugging Features' (scheme-debugging.texi)
by `Using Guile Interactively' and `Using Guile in Emacs'
(scheme-using.texi). Move the `Tracing' content of
scheme-debugging.texi to the Modules section.
* api-options.texi (Evaluator trap options): Move doc for
with-traps and debug-object? to here.
* api-modules.texi (Included Guile Modules): Change reference from
`Debugging Features' to `Tracing'.
* api-evaluation.texi (Evaluator Behaviour): Add reference to
`Evaluator trap options'.
* api-debug.texi (Examining the Stack): Minor improvements to
display-backtrace doc.
* api-debug.texi (Debug on Error): New text on how to catch errors
and the error stack.
* api-debug.texi (High Level Traps): New.
* api-debug.texi (Debugging): New intro text. New subsection
"Evaluation Model". Moved existing subsections "Capturing the
Stack or Innermost Stack Frame", "Examining the Stack", "Examining
Stack Frames", "Source Properties", "Decoding Memoized Source
Expressions" and "Starting a New Stack" under "Evaluation Model".
(Capturing the Stack or Innermost Stack Frame): Some new text, and
correction to doc for last-stack-frame.
(Debug on Error): Renamed from "Interactive Debugging".
* configure.in (AC_CONFIG_FILES): Add emacs/Makefile and
ice-9/debugging/Makefile.
* Makefile.am (SUBDIRS): Add emacs.
directly, and only if GUILE_I was defined by the configure step.
(scm_log, scm_log10, scm_exp, scm_sqrt): Use SCM_COMPLEX_VALUE
code only if SCM_COMPLEX_VALUE is defined.
* configure.in (--without-64-calls): Use AC_MSG_CHECKING and
AC_MSG_RESULT instead of just echo.
(GUILE_I): New programs to try using _Complex_I or 1.0fi for the
imaginary unit.
optimizing out the test. In particular this fixes solaris where there
isn't an isinf or isnan (though gcc still optimizes as if there is).
Reported by Hugh Sasse.
(AC_C_VOLATILE): New.
needed because it's empty, but including it does no harm.
(-lm): Look for "cos" instead of "main", since cos and friends are the
purpose of looking for libm.
(winsock etc): Test $host = *-*-mingw* rather than $MINGW32, autoconf
regards the latter as obsolete.
(AC_MINGW32): Remove test, $MINGW32 now unused.
(uint32_t): Look at HAVE_NETDB_H rather than hard-coding __MINGW32__
in the test program.
* configure.in: Test if need braces around PTHREAD_ONCE_INIT, set
AC_OUTPUT of SCM_I_GSC_NEED_BRACES_ON_PTHREAD_ONCE_INIT.
Need to set SCM_I_GSC_NEED_BRACES_ON_PTHREAD_ONCE_INIT to some value
always, not just when pthreads.
