Wow, we are incrementing an enum here.  Is that legal?  What compiler
are you using?

Possibly C++ doesn't allow that?  But if so, it's user error.
Postgres is written in C not C++.

(I could see a compiler issuing a warning here that forkNum will
get incremented past the declared range of the enum.  But that
doesn't seem to be what's being reported.)

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
