I am not sure this won't fail in certain cases, but in option 2) you can
try making a
/mingw63 as a symbolic link to D:\unix_env\mingw. to do that you need to
run an MSYS shell as administrator and
export MSYS=winsymlinks:nativestrict
prior to invoking
"ln -s /d/unix_env/mingw /mingw64"
(practice this command first, to be sure that it will work as expected).
Alternatively, you could use this the other way by making
/d/unix_env/mingw a symbolic link to /mingw64.

$ echo $MSYS

$ ln -s /mingw64 mingw64
