Comment (by cypherpunks):

 As for `__USE_MINGW_ANSI_STDIO`, now when ucrt is used, mingw-w64 should
 definitely be patched with
 {{{
 -# define __USE_MINGW_ANSI_STDIO 1
 +# define __USE_MINGW_ANSI_STDIO 0
 }}}
 in its ugly defaults:
 https://github.com/mingw-w64/mingw-w64/blob/f8e2c9ac594259fd2a46746943f84bd8766d7054/mingw-w64-headers/crt/_mingw.h.in#L428
