Hi Eric, > From my perspective Win32 is the windows ABI and mingw and cygwin are their own ABIs No. They are using Windows Platform ABI for almost everything (e.g. calling API, C runtime, etc.). At least mingw does. The differences are exactly in unspecified area (e.g. passing / returning structs by value). The only difference is C++, where mingw / cygwin follows Itanium ABI and MSVC - its
