The other main problem after that is that the C++ ABI has been changing, so having only one version of the library would cause trouble. But maybe that is not as big a problem now as it was in the past? OTOH, surely there will be some changes to the library in the future, so it seems that it would be a good idea to be able to have multiple versions of libstdc++.dll.a installed simultaneously? Or is this not possible for some reason? jwe -- 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/
