Currently when linking target application with LTO builds of mingw-w64 libraries, it is needed to manually specify entry point of mingw-w64 crt startup function via linker flag -Wl,-e,_mainCRTStartup (for console executables) or -Wl,-e,_WinMainCRTStartup (for GUI executables) or -Wl,-e,_DllMainCRTStartup@12 (for DLL libraries). Otherwise LTO compiler drops startup function generates output binary totally broken and non-working (executable crashes during during startup).
Wouldn't this cause executables to contain all three entry-point functions, which I think should be avoided?
