* stime.c (bdtime2c): Initialize lt->gmtoff and lt->tm_zone from
sbd_time. (Thanks to Eric Hanchrow.)
Fix from Ken Raeburn <raeburn@raeburn.org>:
* weaks.c (scm_make_weak_vector): Add another extra slot before
vector contents, to be used only during garbage collection.
* weaks.h (SCM_WVECT_GC_CHAIN): New macro to access it.
* gc.c (scm_weak_vectors): Now a SCM instead of a SCM*, and now
static.
(scm_weak_size, scm_n_weak): Deleted.
(scm_igc): Use SCM_WVECT_GC_CHAIN to build up a chain of weak
vectors without allocating new storage during GC, using
scm_weak_vectors as the head of the chain.
(scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
instead of stepping through an array.
(scm_gc_sweep): Update offset used to find start of weak vector to
free it.
(scm_init_storage): Set scm_weak_vectors to EOL.
Fix from Ken Raeburn <raeburn@raeburn.org>:
* gc.c (already_in_gc): New variable.
(scm_igc): Set and clear already_in_gc; abort if it's set at
entry.

Fix from Gary Houston:
* fports.c (local_seek): Signal an error if the seek fails.
* ports.c (scm_lseek): Don't check return value of port's seek
function; it's its job to signal an error if there's a problem.
