The same type of problem exists for `org-latex-to-pdf-process': contrarily to
what I'd thought from reading the doc, the argument %b is NOT (only) the base
name, but the full name without the file extension; hence, the problem under
Cygwin Emacs with /cygdrive/c type of paths which are sent (via LaTeXMK or
directly) to PDFLaTeX.

Hence, my current (ugly) workaround to support PDFLaTeX and XeTeX in both
Windows and Cygwin versions of Emacs:

              "pdflatex -interaction=nonstopmode -output-directory=%o %f")))

    (when (string-match "^#\\+LATEX_CMD: xelatex" (buffer-string))

--8<---------------cut here---------------end--------------->8---

where I convert Cygwin paths to mixed Windows paths (mixed meaning: use
slashes instead of backslashes -- otherwise, the backslashes should be
escaped, which isn't the case).

Best regards,
