* configure: Re-generate after Martin's configure.in patch.
2003-09-13 Martin Buchholz <martin@xemacs.org>
* configure.in (OS_RELEASE): Add support for SunOS 5.10.
On current OSes produced by Sun, `uname -r' prints "5.9".
It seems likely that on future OSes, `uname -r' will print "5.10".
We need to accept multi-digit release numbers.
2003-09-13 Martin Buchholz <martin@xemacs.org>
* s/sol2.h: Use OS_RELEASE=os_release_major*100+os_release_minor

/* code is all from loser.c and loser.el by Mly Copyright (C) 2002 Richard Mlynarik <mly@pobox.com> This is part of XEmacs Compile this file. Run it in the background giving it a command line argument PORT which is a positive integer 1024 < PORT < 32768 (avoid the numbers assigned in /etc/services). Then start up a fresh (you're going to crash) XEmacs. Execute the following (defun lose (port) (interactive "nUrk: ") (require 'comint) (while t (condition-case e (let* ((name "*lose*") (b (get-buffer-create name))) (switch-to-buffer b) (comint-mode) (comint-exec b name (cons "127.0.0.1" port) nil '()) (process-send-string (get-buffer-process b) "\377\373\001") (process-send-string (get-buffer-process b) "\377\373\001")) (error (message "URK: %s" e)) (sit-for 1)))) Then M-x lose RET PORT RET and you lose big (in XEmacs 21.1, anyway). Note: the error messages are proper functioning. What should eventually happen after a number of SIGPIPEs is that you get a SIGSEGV and life is bad and XEmacs is dead. */ #include <arpa/inet.h> int main (int argc, char **argv) { struct sockaddr_in junk; int s; memset (&junk, 0, sizeof (junk)); junk.sin_family = AF_INET; junk.sin_addr.s_addr = htonl (INADDR_ANY); /* un*x sucks */ junk.sin_port = htons (atoi (argv[1])); /* un*x blows */ s = socket (PF_INET, SOCK_STREAM, 0); bind (s, (struct sockaddr *)&junk, sizeof (junk)); listen (s, 1); for (;;) { int loser = accept (s, NULL, 0); close (loser); } }
