He wasn't brave. He was stupid. He didn't understand what glibc was supposed to be providing and he wouldn't understand it even when it was explained to him. >I'm really seeing the non-optimized cygwin cp behaviour causing bad >reputation, which could be easily patched and maybe even accepted >upstream. Who knows. Eric what do think? Would it be worthful to think >about? If this is what you want then you should look into a non-cygwin solution. There are a couple of projects which provide GNU tools for Windows without resorting to something like the Cygwin DLL. Also, don't you see something wrong with the mindset of "Windows Fast. Cygwin Slow. So, must use straight Windows functions." without even bothering to do any research into what is causing the slowness? How do you, or anyone who cares about this know that this "problem", know that it isn't correctable without resorting to patching cp? cgf -- 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/
