Yes, we were talking about a CYGWIN environment variable. It would probably be something like "arch_mismatch". However, you're jumping to implementation when it isn't even clear if this is something that we want to do. >And what about the other direction? Apparently "vice versa" is not a universally understood term. >It is clear that some operations cannot occur especially pty but that >is still true with execing any Windows program. I don't see this >being too big an extra burden on support. If people don't understand why their Windows programs don't understand Cygwin ptys I'm sure that they won't understand why their Cygwin programs don't understand Cygwin ptys. We just, in fact, already saw this confusion, mainly because the error was even more confusing than normal. 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
