change makes the evaluator safer at the cost of evaluation speed.
It handles the case when the user has added a non-immediate
improper end of the application form, e.g., `(+ 0 . x)'.
(Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
minimize the extra cost as much as possible. The new code is
enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
problem with structs planted directly in the code (e.g. by a
macro). This no longer causes segmentation fault. (Thanks to
Eric Hanchrow.)
* eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
arg `proc' in order to be able to throw errors; New argument
checking code.
(scm_usleep): Return SCM_INUM0 on those systems.
* coop.c (usleep): Return void on some systems.
* configure.in: Define USLEEP_RETURNS_VOID on some systems.
scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
A section.
* __scm.h: Start the long-term project of moving to POSIX threads.
Phase 1: Classification of all critical sections.
(SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
for A sections. (See comments in __scm.h for details.)
nonblocking through the use of scm_internal_select.
* emacs.scm: Removed use of nonblocking.scm.
* gwish.scm, gtcl.scm: Removed. tcltk.scm has made these
obsolete.
cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
(libpath.h, versiondat.h): Replaced dependency on Makefile with
dependencies on $(srcdir)/Makefile.in
$(top_builddir)/config.status in order to avoid circularity.
* configure.in (GUILE_LIBS): New variable. Contains libraries
which libguile needs to be linked with. Substituted into
libpath.h.
* threads.m4 (threads_package): Don't add $LDFLAGS and $LIBS to
$cy_cv_threads_libs.
procedure apply: Copy argument lists before pushing them unto the
environment so that the environment won't get mutated due to
manipulation of procedure arguments. This should perhaps be
regarded as a temporary solution until someone finds a more
efficient one. (Thanks to Maciej Stachowiak.)
* ltconfig, ltmain.sh, config.sub, config.guess: Updated.
New automake: 1.3
* Makefile.in, aclocal.m4, configure: Regenerated.
* README: Mention new version numbers on libtool and automake.
* ltconfig, ltmain.sh, config.sub, config.guess: Updated.
New automake: 1.3
* Makefile.in, aclocal.m4, configure: Regenerated.
* README: Mention new version numbers on libtool and automake.
warning.
* eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
to avoid compiler warnings.
* dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
from debug.c --> eval.c
* eval.h, eval.c (scm_eval_options_interface): New options
interface.
(SCM_EVAL_STACK): New option: Size of newly created stacks,
i.e. stacks for new threads.
* eval.c (unsafe_setjmp): Removed with #if 0.
* eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
to avoid compiler warnings.
(was 1). (Interface changed according to suggestion by Per
Bothner.)
* backtrace.c (display_header): Add 1 to line and column numbers
when presenting them to the user.
