This was a bit prematurely. There is a big problem with this aproach: it changes current directory of the process. So you can't really use it in multithreaded or signalled environment. So chdir is not a real solution. Is it really that hard to workaround the problem in cygwin? -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
