I think just using the default C:\msys64 might be clearer than using
this kind of meta-syntax.

Actually I never changed my Windows PATH. Running Emacs 25 outside of
the MSYS2 environment complains about not finding libwinpthread-1.dll,
but Emacs 26 works fine. Perhaps we can just remove this section
entirely?

Is there some reason you changed to a for loop?

Do you mean that your fstab file was broken somehow? I never even
looked at mine.

Do you mean you needed to modify your ~/.bashrc to get the correct
PATH under mingw64.exe? It should already be set correctly by
/etc/profile.

Perhaps we can put this under a "Troubleshooting" section at the end.
