from pairs with a GLOC in the car.
* symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
otherwise `symbol-hash' will behave badly.
(scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
we get segmentation fault!
* symbols.c: Added #include "weaks.h". New functions
`builtin-bindings' and `builtin-weak-bindings'. (These will be
moved to an extraneous library when we split libguile.)
old scm_sysintern but doesn't take a second value argument.
(scm_sysintern): Now uses scm_sysintern0.
(scm_sysintern_no_module_lookup): Renamed to
scm_sysintern0_no_module_lookup and doesn't take a second value
argument any longer.
* symbols.h (scm_sysintern0: Added declaration.
* options.c (scm_init_opts): Use scm_sysintern0 instead of
scm_sysintern when interning option keys. Otherwise we risk
destroying the values of already interned variables.
* symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
scheme-level boolean (use SCM_NFALSEP).
* backtrace.c (scm_init_backtrace): Make Scheme-level variable
`the-last-stack'.
(scm_backtrace): New function. (C version of old function from
boot-9.scm) Motivation: Make it possible to display backtraces
without depending on boot-9.scm. (I'm uncertain if this
motivation is good enough...)
* root.h (scm_root_state): Add member the_last_stack_var.
(scm_the_stack_var): Defined to scm_root->the_last_stack_var.
* root.c (mark_root): Mark scm_the_last_stack_var.
* init.c (scm_start_stack): Initialize scm_the_last_stack_var to
SCM_BOOL_F.
scm_sysintern_no_module_lookup.
(scm_sysintern): New function to take the place of the old
scm_sysintern. It uses the current toplevel lookup closure to give
the symbol its value. This is a temporary hack to put packages
like gtcltk into their own module.
(scm_can_use_top_level_lookup_closure_var): New variable to tell
us whether `scm_top_level_lookup_closure_var' has been initialized
and is usable.
* eval.c (scm_init_eval): Set it.
ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
for obtaining the address of a car or cdr field. Motivation:
&SCM_CXR make assumptions about the internal structure of the
SCM_CXR selectors.
* alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
vports.c: Cleaned up use of pairs: Don't make any special
assumptions about the internal structure of selectors and
mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
(Among other things, this change makes it easier to build Guile
with certain compilers which have problems with casted lvalues.)
array; use it appropriately. Since GCC is quite happy to
subscript functions, it never warned us about this; we should use
-Wpointer-arith in the future. I guess we never tested
case-insensitivity.
