--- Comment #12 from Bernhard Übelacker bernhardu@mailbox.org --- I am sorry, but I don't get it configured with "Debian clang version 11.0.1-2", if there is just clang installed without gcc or mingw.
configure: error: The compiler doesn't support -mabi=ms. Use gcc instead of clang, or install mingw-w64. config.log: error: '__builtin_ms_va_start' used in System V ABI function
