So, I did this:

 - Installed a fresh msys to a clean directory on my desktop.
 - Dropped the emacs-no-deps.zip directory on top of the mingw64 directory.
 - clicked on runemacs.exe from windows shell -- Emacs fails to launch
   because of libgmp
 - pacman installed all the dependencies of Emacs
 - clicked on runemacs.exe -- Emacs launches, native-comp fails as
   described
 - run mingw64 shell form the mys installation
 - ./runemacs.exe in that shell
 - Emacs launches, native-comp works
 - ~/ and thus ~/.emacs.d/eln-cache is a different location with the two
   launch methods

I believe that msys is mostly portable and a new installation is nearly
clean (except for .bashrc and such like).

Conclusions:

 - emacs is picking up dependencies from mingw64 run in either way,
   because otherwise it wouldn't run at all from the shell
 - Emacs is picking up the environment from mingw64 when launched from
   within it, hence the differences in location of ~
 - Native-comp has everything it needs to run, or it couldn't run at
   all.
 - It is missing something from the environment when run in the windows
   shell.

This is export run inside the mingw64 window. So, lots of options there.
