This looks like problems with failing to quote paths with embedded

would hope have no relevance to your build,
Difficult to believe it is a cygwin version problem.

Re: admin privileges when logging in by ssh?
When a user with administrative privileges logs in to sshd, it seems that the user is only granted standard user privileges for that session. Is there a way around that? How can I get the admin privileges for that session? Winding this up: Password authentication to sshd is all that's needed to be granted the account's admin privileges on login. I was mistaken about UAC: unlike at the console, when you log in by ssh, the account's admin privileges are granted at login, without needing any further authentication to UAC. Thanks very much Eliot and Karl, for your answers about UAC. Although it turns out that they're not needed in this case, they're likely to be useful some other time.

Re: core dump using Make 3.81
Hello all, Matthias Bauer had reported an error in the OpenOffice.org build using Make 3.81 back in February [1]. I'm writing today to mention that I ran into what I believe to be the same issue when working on another project. I'm working on an OpenCL program that is being built under Cygwin in Windows. Make 3.81 crashes every time that I try to use it to build my program: /bin/sh: line 1: 232 Aborted(core dumped) /usr/bin/make --no-print-directory target=$t make: *** [.DEFAULT] Error 134 I downloaded the source for Make 3.82 from gnu.org, installed it to /usr/local/bin, and the crash goes away as Matthias also reported for OO.o.

nosleep command
I'd like to provide a 'nosleep' command for Cygwin, that will prevent the host from sleeping or hibernating while a command executes. I haven't seen anything in Cygwin that currently does this, but please enlighten me if I'm wrong. Looking around for how to do this, I see two basic approaches: (1) Run SetThreadExecutionState(ES_CONTINUOUS | ES_SYSTEM_REQUIRED) to try to convince the computer not to sleep or hibernate, while the desired command executes. See for example [1], which does this. I haven't tested it yet. Looking at the documentation of SetThreadExecutionState() [2], it seems that this approach will keep the computer from sleeping when it's idle, but not when the user closes a laptop lid or pushes the power button. (2) Use the powercfg command (or PowerDuplicateScheme(), etc.) to create a temporary power scheme with sleep and hibernation disabled, then restore the original power scheme after the command has finished. See for example [3], which does this (that particular implementation needs work - powercfg needs different options in Windows XP and earlier). Which approach do people think is better? Or is there another, better way? #2 seems more fragile, in the sense that it will fail to restore the original power scheme if the parent process is killed before it finishes executing. By contrast, #1 doesn't have any cleanup to do at the end, so there's no harm done if the parent process is killed. #2 will prevent the user from manually putting the computer to sleep or hibernating, but I'm not sure if that's an advantage. Users won't necessarily know why their computer won't go to sleep when they tell it to, or why after a while it starts to work again. Whether it's worthwhile may depend on how important it is for the requested command to finish - although that still isn't guaranteed under #2, since the user can still shut the machine down. Finally, it seems likely that #1 needs lower privileges than #2, although I'm not sure about that yet.
