write_void_port, flush_void_port, getc_void_port, close_void_port,
noop0): Use ANSI prototypes instead of K&R declarations, so the
initialization of void_port_ptob gets aggressively type-checked.
Fix arguments of print_void_port and write_void_port. (Bill
Janssen)
here; apparently it's not quite right to have const in a prototype
and then use a K&R declaration. I wonder if stuff like this will
go away if we compile with -Wrequire-prototypes, or whatever that
is...

throw.c: Update copyright years; these files have been worked on
significantly in 1997, but only had copyright years for 1996.
Also, change name of copyright holder on some from Mikael
Djurfeldt to Free Software Foundation; he has signed papers
assigning the changes to the FSF.
Return #f on end-of-file when scanning table (i.e. when called
with no arguments). Try to catch errors, when we can.
* posix.c (scm_getgrgid, scm_getpwuid): Same.
select, since they were not used in this file.
* * filesys.c (scm_select): make the fifth parameter microseconds,
not milliseconds. let the fourth parameter be either a real value
or an integer or #f. The first, second and third arguments can
now be vectors: the type of the corresponding return set will be
the same.
(set_element, get_element): new static procedures.
* net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
Use a meaningful error message when signalling an error. For
this, scm_gethost must check h_errno rather than errno.
scm_misc_error.
* stime.c (scm_localtime): copy the result of localtime before
calling gmtime in case they share a buffer.
(scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
nor HAVE_TZNAME.
sure how this was supposed to work.
(scm_async_click): don't send SCM_TICK_SIGNAL.
(scm_init_async): don't initialize %tick-thunk.
* the following change doesn't affect the Scheme interface:
gc-thunk is called at the end of garbage collection. however it's
no longer implemented by pretending it's a signal.
* gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
system async corresponding to scm_gc_thunk.
* async.h: declare scm_gc_async.
* async.c (scm_sys_gc_async_thunk): apply the thunk named by
gc-thunk directly, instead of going through a signal handler.
(scm_gc_async): new variable, points to the GC system-async.
(scm_init_async): save the GC async as scm_gc_async instead
of using system_signal_asyncs.
(scm_gc_vcell): new variable, stores the gc-thunk vcell.
