When you use GDS to evaluate Scheme code from Emacs, you can now use
`C-u' to indicate that you want to single step through that code. See
`Evaluating Scheme Code' in the manual for more details.
* scheme-using.texi (Evaluating Scheme Code): Document use of
`C-u' prefix with evaluation commands.
* gds-scheme.el (gds-eval-region, gds-eval-expression)
(gds-eval-defun, gds-eval-last-sexp): Support `C-u' prefix,
meaning that user wants to single step through the code.
* gds-client.scm (handle-nondebug-protocol): Add support for
setting a trap on code that is about to be evaluated.
* configure.in: Update stack direction test to be like that in
Autoconf _AC_LIBOBJ_ALLOCA and Gnulib; specifically in involving a
function calling itself.
forever, and are known to conflict on some platforms with that
provided by <errno.h>, which we include unconditionally. If
<errno.h> doesn't provide a errno declaration, what is the point
of it?
Guile CVS to build-aux and guile-readline.
* HACKING: Note need for libtool >= 1.5.26.
* config.rpath, build-aux/config.rpath: Updated to latest upstream
version.
* config.guess, config.sub: 2008-01-07 versions added to Guile
CVS, to ensure that Guile developers are using new enough versions
(in particular for AIX 6.1 support).
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.
scm_set_thread_cleanup_x, scm_thread_cleanup): Lock on thread-specific
admin mutex instead of `thread_admin_mutex'.
* threads.h (scm_i_thread)[admin_mutex]: New field.
* throw.c (make_jmpbuf): Don't enter critical section during thread
spawn -- there is a possibility of deadlock if other threads are
exiting.
