I'm wondering if this was the desired result or not? (This is not a new problem, it's been around for at least a year of releases). It makes some makefiles not work as expected, specifically, the GCC manual describes how to perform auto-dependency analysis like: gcc ... | sed ... But, if gcc fails, sed will still work, thus make will not consider it a failure and will continue. I know there are many ways to avoid this specific problem, already implemented one. Just wanted to let you guys know. -Rolf Campbell Software Designer Tropic Networks -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
