--- Comment #2 from freezer at posteo dot de --- That's too bad. For my use case it would be more efficient if I passed the file directly to gcc through stdin. There is really no way to change this, maybe through an option? With clang this works as expected. The same diagnostics are printed independent of whether the file was passed through stdin or as a command-line argument.
