This sounds like the build of the crt happens with old/incorrect versions of the headers somehow. If you look in mingw-w64-headers/crt/stdio.h, you'll find the missing definitions of UCRTBASE_PRINTF_LEGACY_WIDE_SPECIFIERS and __stdio_common_vfwprintf. ucrtbase_compat.c does undefine __MSVCRT_VERSION__ and redefine it to 0x1400 before including any header, so it should have the right value to make these declarations visible.
