No, it really doesn't. It is just a library that uses cygwin functions. >but it sounds interesting (especially if it allows less-frequent >invocation of the rebaseall ritual). Since the VAST majority of UNIX/linux programs use fork/exec I don't see how this would really have much of an effect. cgf -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
