fat "hello word" regression
mingw64-64 was updated from v7.0.0 to v10.0.0. That means that __USE_MINGW_ANSI_STDIO is defined 1 by default now due to this commit: https://github.com/mingw-w64/mingw-w64/commit/bfd33f6c0ec5e652cc9911857dd1492ece8d8383 You can revert the non-standard compliant behavior by passing -D__USE_MINGW_ANSI_STDIO=0 on command-line.
