--- Comment #2 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- A configure test can only test what sprintf does for the host, not for the target, so this would always need to be a target hook. Even with a hook, it would not surprise me if e.g. results on MinGW depend on __USE_MINGW_ANSI_STDIO, so you can't assume there is always a constant answer for these questions.
