--- Comment #13 from Jonathan Wakely <redi at gcc dot gnu.org> 2012-10-23 13:10:40 UTC --- (In reply to comment #9) > Created attachment 28191 [details] > Enabling string conversion functions in MinGW > > Patch from: http://tehsausage.com/mingw-to-string That's a zip file, not a patch. I've fixed the attachment details. Maybe tehsausage's alternative implementations could be used under different names so they don't replace the system functions, and have mingw use those alternative names. The changes don't look significant enough to need a copyright assignment/disclaimer anyway, they just forward from one function to another. The configure check that sets _GLIBCXX_HAVE_BROKEN_VSWPRINTF could check for working _vsnwprintf and make that usable instead.
