Re: Fwd: Compatibility of binaries built with one version of cygwin with other versions of cygwin

Re: Compatibility of binaries built with one version of cygwin with other versions of cygwin
"Guaranteed" might be a strong word - especially given the lack of a guarantor; probably depends on whether the programmer has had to workaround any nuances in the Cygwin library that may have changed in later versions. I think the library function exports have been the same for awhile and I've personally had pretty good lucking simply dropping in a new DLL file without issues. -- 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
