* error.h (scm_error, scm_syserror, scm_syserror_msg,
scm_sysmissing, scm_num_overflow, scm_out_of_range,
scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
scm_misc_error): Tell GCC that these functions never return.
* struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
out the field type, call abort if SCM_ASSERT returns, to placate
the optimizer.
* stacks.c (scm_make_stack, scm_last_stack_frame): abort if
scm_wta ever returns. We can't handle this case anyway, and this
gives the optimizer more information.
* unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
scm_wta ever returns.
(scm_must_malloc, scm_must_realloc): Added a hysteresis to the
rules for raising scm_mtrigger. Previously, unfortunate but not
unlikely circumstances could result in almost constant invokation
of the gc. Now, this situations should be less likely, but they
are not prevented completely.
scm_string_set_x scm_string_equal_p scm_string_append):
Bugfix according to scm patch from Aubrey Jaffer:
Corrected long-standing
(not (eqv? (integer->char 128)
(string-ref (make-string 1 (integer->char 128)) 0)))
bug found by John Kozak <jk@noontide.demon.co.uk>.
renamed from display_error_message.
* backtrace.h (scm_display_error_message): Added extern decl.
* throw.c (uncaught_throw): Use it to display the error message.
machine-dependent C and assembler files qtmds.o and qtmdc.o, but
using -c and -o together on the cc command line isn't portable.
* configure.in: Generate the names of the .o files here, and
substitute them into Makefile.
* Makefile.am (qtmds.o, qtmdc.o): Let CC name them what it wants,
and then rename them when it's done.
(configure, Makefile.in): Regenerated.
Scheme.
* throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
(scm_internal_catch): New function, replaces...
(scm_catch_apply): Deleted.
* throw.c (scm_catch_apply): Deleted; replaced with a more general
mechanism which is a bit more code, but can be used nicely from C
and implement the Scheme semantics as well.
(scm_internal_catch): This is the replacement; it's named after
the analogous function in Emacs.
(scm_catch): Reimplemented in terms of the above.
(struct catch_body_data, catch_body, catch_handler): New
functions, used by scm_catch.
* root.c (cwdr): Reimplemented in terms of scm_internal_catch.
(struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
support for new cwdr.
