If lacking a full prototype is the problem and there is no function prototype, add one in an appropriate .h file (or make the partial prototype complete). If compiling a library, make sure that a new prototype doesn't affect backwards compatibility with older applications using the library. If it's not possible to add a prototype, you can add the ''-std=gnu17'' compiler option (e.g. by appending to ''CFLAGS'' before the build step) to revert to the old behaviour (but don't do this to fix a library because it means that all applications using the library will also need to add the flag). If there ''is'' a prototype but it does not match the number of arguments passed in, then it is a compatibility break, likely with some dependent library, and the application will need to be patched to use the correct arguments.     Added for mga10. Added for mga10.
