--- Comment #4 from Stas Sergeev <stsp at users dot sourceforge.net> --- (In reply to Jonathan Wakely from comment #3) > It seems like you might be expecting more from -fpermissive than it actually > provides. It only affects a very limited set of diagnostics, and isn't a > general "compile invalid code" switch. I always used it to compile the (valid) C code in C++ mode. I thought that's what it is for. It violates the C++ standard up and down. And that -Wnarrowing case is "better" than others because it was a warning in c++03. Other problems that -fpermissive allows, were always an errors in any c++ mode.
