[Mingw-w64-public] Patch: Fix stack overflow in __mingw_wcstof and __mingw_wcstold

Hi, the attached patch fixes a stack overflow in __mingw_wcstof and __mingw_wcstold. I've also attached a small reproducer for the bug. Interestingly the bugged functions are only called if using C++ and if windows.h is included before wchar.h Regards, Tim Kosse

[Mingw-w64-public] Patch: wcsrtombs with null dst must ignore len

Hi, there's a bug in wcsrtombs (mingw-w64-crt/misc/wcrtomb.c) if null is passed as destination buffer. In this case, wcsrtombs does not ignore the len argument. Yet, according to the C99 standard, if the dst is null, the len argument is ignored. The attached patch fixes this bug. Regards
