You can pick up the most current one at the same place you likely picked up the original, on the Cygwin home page http://cygwin.com/ . Look on that page for a link to setup.exe . Click that link. That'll pull the current setup.exe onto your machine. Put it in the same location you put the original setup.exe.

[ANNOUNCEMENT] Updated: cygwin-1.7.10-1
Hi Cygwin friends and users, I just released 1.7.10-1. It introduces a couple of new APIs and some changes which are supposed to reduce fork problems. And lots of other stuff. Just read on. for a start, here are the most distinct changes from old behaviour: - 1.7.10 drops support for Windows NT4 to reduce the amount of legacy code. - The CYGWIN=tty mode has been removed. Either just use the normal Windows console as is, or use a terminal application like mintty. - New heap management. Drop registry setting heap_chunk_in_mb entirely in favor of a new per-executable setting in the executable file header which can be set using the peflags tool (see `peflags --cygwin-heap'). As always, please have another look into the documentation at http://cygwin.com/docs.html. It contains a few improvements and the description for new features and changes from old behaviour. What's new: --- - New getconf tool for querying confstr(3), pathconf(3), sysconf(3), and limits.h configuration. - New tzset utility to generate a POSIX-compatible TZ environment variable from the Windows timezone settings. - The passwd tool now allows an administrator to use the -R command for other user accounts: passwd -R username. - Experimental: Change the way sockets are created so that Cygwin always circumvents so-called layered service providers (LSPs) starting with Windows Vista. - signal handler functions are now dispatched in threads other than the main thread. - Support NcFsd filesystem. - clock_gettime(3) and clock_getres(3) accept per-process and per-thread CPU-time clocks, including CLOCK_PROCESS_CPUTIME_ID and CLOCK_THREAD_CPUTIME_ID. - New pthread functions: - Spin Locks: pthread_spin_destroy, pthread_spin_init, pthread_spin_lock, pthread_spin_trylock, pthread_spin_unlock. - Stack management: pthread_attr_getstack, pthread_attr_getstackaddr, pthread_attr_getguardsize, pthread_attr_setstack, pthread_attr_setstackaddr, pthread_attr_setguardsize, pthread_getattr_np. - Clock Selection: pthread_getcpuclockid, pthread_condattr_getclock, pthread_condattr_setclock. - Scheduling: pthread_setschedprio. - Signalling: pthread_sigqueue. - Add /proc/devices, /proc/misc, /proc/sysvipc, /proc/swaps. - Make various system functions thread cancelation points per POSIX. - Add ioctl FIONREAD handling for non-sockets. - dlopen now supports the Glibc-specific RTLD_NODELETE and RTLD_NOOPEN flags. - The printf and wprintf families of functions now support the %m conversion flag. - Execed processes now inherit the children of their predecessor. - Fifos have been rewritten and should now be more reliable. - GNU/glibc error.h error reporting functions: error, error_at_line, error_message_count, error_one_per_line, error_print_progname. - C99 tgmath.h type-generic macros. - Other new API: clock_getcpuclockid, clock_nanosleep, clock_settime, __fpurge, get_current_dir_name, getgrouplist, getpt, ppoll, psiginfo, psignal, ptsname_r, sys_siglist, sysinfo. - cygwin_conv_path_list finally supports CCP_WIN_W_TO_POSIX and CCP_POSIX_TO_WIN_W conversions. What changed: - - Drop support for Windows NT4. - The CYGWIN=tty mode using pipes to communicate with the console in a pseudo tty-like mode has been removed. Either just use the normal Windows console as is, or use a terminal application like mintty. - The CYGWIN environment variable options envcache, strip_title, title, tty, and upcaseenv have been removed. - New heap management. Drop registry setting heap_chunk_in_mb in favor of a new per-executable setting in the executable file header which can be set using the peflags tool. Drop registry setting heap_slop_in_mb entirely. - Revamp console and pseudo tty handling. Rename /dev/ttyX to /dev/consX, /dev/ttyX to /dev/ptyX. - Improve fork/exec performance on 64 bit systems. - Improve Ctrl-C handling in console. - Try harder to let fork not fail if DLLs are moved in memory which should, in some cases, minimize the need for rebaseall. - Try harder to send SIGHUP to children when process group leader fails. - Deal with Windows problem where non-blocking pipe I/O was not flushed properly on close. - Attempt to regularize most syscall-related strace output. - Improve behavior of Cygwin when started from a 64-bit process, especially under Windows 2003. - Improve multi-thread/reentrancy safety with syscalls that deal with fds. - dlopen can now find cygFOO.dll, even if the caller specified libFOO.so. This is supposed to support applications which are no aware of Windows DLLs. - Make accept(2), poll(2) and shutdown(2) behave more like on Linux. - Raise max number of mount points from 30 to 64. - Output of /proc/maps is closer to what Linux prints and much more useful to examine process VM layout. - /proc/loadavg now shows the number of currently running processes and the total number of processes. - /proc/version now

What accounts on what machine from where?!? The CYGWIN=tty setting is neither set by sshd itself, nor is it set by the ssh-host-config script by default. Somebody must have created this manually. It's probably a setting in the sshd server entry. Look for the service registry entry HKLM/SYSTEM/CurrentControlSet/services/sshd/Parameters/Environment If it's not set there, it could be set in ~/.ssh/environment, or in ~/.ssh/rc, or in the ~/.ssh/authorized_keys file. Alternatively it's a setting done in the user's profile on the target machine. Or in the global Windows environment.

This happens whenever one ssh's from a Linux box to a Windows XP box with Cygwin on it. On login one gets the warning about CYGWIN having the value tty in it. The users on the windows systems don't have CYGWIN set on any of their profiles, .login's .cshrcs's etc. etc. BUT, /HKLM/SYSTEM/CurrentControlSet/services/sshd/Parameters/Environment IS set to ntsec binmode tty on the Windows XP boxes. -- Harry G.

extremely rarely fork errors: who occuppies the space?

Rebaseall and peflagsall were running. We have this error really not reproduceable on some compile machines. These machines are running a perl script which polls a remote database for running make jobs in parallel (-j flag) - that's all. Normally all works fine - but sometimes we got these fork errors. Is there an possibility to get more information who is occupying the address space? Perhaps I can instrument the cygwin1.dll to wait or do something special - so I can use other tools i.e. sysinternals vmmap, process explorer ... to have a look who is using this address space. Perhaps a self build debug snapshot version with instrumented debug flags will give me some hints? Please - can anyone give me some hints.
