And that exactly is the bug. GCC cannot simultaneously be Windows-compatible, and also support extended precision floating point under the name "long double". > According to http://msdn.microsoft.com/en-us/library/9cx8xs15.aspx it is > MSVC limitation. Therefore, mingw should also implement that limitation, to be binary-compatible with MSVC. Since binary compatibility is an explicit goal of mingw, failing to provide binary compatibility is a bug.
