* gc.c (scm_gc_sweep): Prepend each segment's free cells to its
freelist, rather than wiping out the old value. (Thanks to Marius
Vollmer.)
* gc.c (which_seg, scm_map_free_list, scm_newcell_count,
scm_check_freelist, scm_debug_newcell): New functions and
variables, for debugging freelist problems.
* pairs.h (SCM_NEWCELL): New debugging version added.
* gc.h (scm_debug_newcell): Added extern declaration, used by
debugging version of SCM_NEWCELL.
scm_check_freelist, scm_debug_newcell): New functions and
variables, for debugging freelist problems.
* pairs.h (SCM_NEWCELL): New debugging version added.
* gc.h (scm_debug_newcell): Added extern declaration, used by
debugging version of SCM_NEWCELL.
pointer to the stdio stream before calling scm_setbuf0, so the
latter will be able to retrieve it. I'm surprised this didn't
segfault earlier. (Thanks to Christopher Lee.)
be #included at all.
* aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
* configure.in: Call it.
* acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
* posix.c, filesys.c: Use its results to decide whether or not to
#include <libc.h>.
* configure, scmconfig.h.in: Rebuilt with autoconf and
autoheader.
number of stack narrowing specifier pairs. The first specifier in
a pair controls inner border, the second the outer border. A
number means cut that number of frames, a procedure object means
cut until that object is found in operator position in a frame.
SCM_CONSP since this is a macro!; Set vframe.prev to
scm_last_debug_frame instead of 0. In this way we can look
"above" the virtual start stack frame if we wish.
(scm_debug_hang): New function: Useful for debugging Guile in
certain tricky situations. Will probably be removed later...
macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
the main code in these macros duplicated and spread over multiple
files. Renamed SCM_THREADS_SWITCHING_CODE ->
SCM_THREAD_SWITCHING_CODE.

aren't enabled by default any longer (they are switched on in
debug.scm). But during development we want to have them also
*inside* boot-9.scm. Therefore, two lines are added at the
beginning of boot-9.scm to enable these.
