check. Correctly check for struct printer tag.
* boot-9.scm (with-regexp-parts): Comment this out. It has no
users in the core, and relies on mildly hairy details of the old
regexp interface.
* boot-9.scm (ipow-by-squaring, butlast): Fix uses of outdated
function names.
* boot-9.scm (with-excursion-getter-and-setter, q-rear): Doc
fixes.
(expect-port, expect-timeout, expect-timeout-proc,
expect-eof-proc, expect-char-proc, expect, expect-strings,
expect-select): Make these public definitions.
(expect-strings): Use make-regexp and regexp-exec, instead of
regcomp and regexec. We've omitted the REG_NEWLINE flag; hope
that's okay.
make-struct-printer, set-struct-printer-in-vtable!): New bindings
to support printing of structures.
(record-type-vtable, make-record-type): Add slot to hold printing
function and initialize it with something appropriate. Removed
commented out printing code.
(record-type-name, record-type-fields): Adjusted slot offsets.
(%print-module): Reduce argument list to "mod" and "port".
* _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
loop.
* posix.c (scm_uname): interpret only negative values as an error.
Solaris normally returns a positive value.
* script.c (scm_compile_shell_switches): if we are not going into
an interactive repl, set scm_mask_ints to zero so that asyncs can
run.
* simpos.c (scm_system): don't ignore/unignore signals around
the "system" call.
* posix.c (scm_open_pipe): don't ignore/unignore signals around
the "popen" call.
* init.c (scm_boot_guile_1): don't call scm_init_signals, it's
done in boot-9.scm instead.
* scmsigs.c, async.c: Major rewriting of signal handling code.
(scm_sigaction): new procedure.
(scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
timing.
(scm_raise): return unspecified, throw error on failure.
* boot-9.scm: signal-handler, alarm-thunk: removed.
don't define ticks-interrupt etc.
top-repl: install signal handlers for SIGINT, SIGFPE, SIGSEGV, SIGBUS
during call to scm-style-repl.
* acconfig.h: mention HAVE_RESTARTS.
* configure.in: check for sigaction and restartable system calls.
basic-load. This is probably wrong, but hopefully the entire
source access system will be revised soon anyway, and this will
make require behave more like Emacs Lisp's require. If this
breaks something, please let me know. Maybe this is real dumb.
