Then the kpsewhich binary must really be the official texlive version.
I'm a sort of giving up.
I suppose this can hardly be the case, `call-process' might not call the
same binary.  What does (executable-find "kpsewhich") return?  On my
w32 emacs 25.2, it returns "c:/texlive/2017/bin/win32/kpsewhich.exe".
