Hysterical raisins. ;-)

Ah, so same versions.  I think the elc files should be platform-agnostic
but I'd try to recompile them with the cygwin emacs anyway to rule that
possibility out.

As said, it shouldn't be a problem but who knows.  BTW, you use auctex
from GNU ELPA, not from MELPA (Milkman's ELPA), right?

Very strange.  So the very same command issued by AUCTeX doesn't find
your tex master wheras it just works from the command line.  The only
thing that would explain things is that it's run from a wrong directory
in the AUCTeX case.

When you do `C-c C-c latex RET' followed by `C-c C-l' to switch to the
output buffer, what does `C-h v default-directory' return in there?  It
should be the directory containing haie-ecm.tex.
