Ah yes this is my conf faults here, I don't know if this either msys2 bug
or mingw32-make.exe. Firstly, I moved make.exe to some folder, I thought
that make.exe was name polluting with my mingw32-make and brought make.exe
back to msys /usr/bin folder. And the error happen. I should compile enter
sh.exe mode and type /usr/bin/make.exe -j2 instead of make -j2.

I have another struggle that when would be compilable release postgresql
for native MSVC2015 build came out? I have another needs for using
plpython3 on windows or this should be moved to another bug report
postgresql vs2015 build ? thanks
