Compilation on MINGW64 fails (CODESET,wcstok,...)
I am using the latest MINGW64 (http://repo.msys2.org/distrib/x86_64/msys2-x86_64-20190524.exe)
Versions: Python-3.7.2, Python-3.8.0b3

$ gcc -v
Using built-in specs.
COLLECT_GCC=C:\msys64\mingw64\bin\gcc.exe
COLLECT_LTO_WRAPPER=C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/9.1.0/lto-wrapper.exe
Target: x86_64-w64-mingw32
gcc version 9.1.0 (Rev3, Built by MSYS2 project)

Result of make:
