* error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
* strings.c (scm_string_ref): make the 2nd argument compulsory.
previously it defaulted to zero for no good reason that I can see.
use a local variable for SCM_INUM (k). replace
SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
(scm_makfromstr): cosmetic changes.
(scm_string): Accept only chars in the list, not strings, for
conformance to R5RS (particularly for list->string, which is
supposed to be the inverse of string->list.) remove
SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
scm_makstr handles the cell allocation. when reporting wrong-type
arg, don't report the position as 1.
* posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
* boot-9.scm (find-and-link-dynamic-module): pass strings, not symbols,
to string-append.
fill_select_type, set_element): modified so that Scheme
"select" tests port buffers for the ability to provide input
or accept output. Previously only the underlying file descriptors
were checked. Rewrote the docstring.
* expect.scm (expect): don't call char-ready? before expect-select,
since select now checks port buffers itself. don't bother to check
the time first either, since expect-select does it.
Emacs 20.5.
* acconfig.h: add LOCALTIME_CACHE.
* These changes should make it unnecessary to call tzset from
Scheme after modifying the TZ environment variable, even if the
system date facilities cache the value.
* stime.c (setzone, scm_localtime): added comments.
(tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
(setzone): don't call tzset.
(restorezone): call tzset only if HAVE_TZSET is defined.
(scm_tzset): don't define if HAVE_TZSET not defined. Change the
doc string to indicate that this procedure isn't likely to do
anything useful.
(scm_localtime, scm_strftime, scm_mktime): call tzset if
LOCALTIME_CACHE is defined.
scm_lookupcar1: throw an error with key 'unbound-variable instead
of 'misc-error when an unbound variable is encountered.
* filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
scm_symlink, scm_readlink, scm_lstat),
posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
scm_sync),
simpos.c (scm_system),
stime.c (scm_times, scm_strptime):
move the HAVE_XXX feature tests out of the procedure bodies.
don't use SCM_SYSMISSING.
scm_validate.h (SCM_SYSMISSING): removed.
error.h, error.c (scm_sysmissing): comment that this is deprecated.
