bug#31079: Windows - Emacs-25.3.1 Can't find source.tex file

[gojjoe]

Hi Liyu and Ikumi,

Here: Windows 7 32-bit, Emacs 25.3.1, and AUCTeX 12.1.1 from elpa, and the file 
compiles smoothly for me too. I have no clue where the problem could be. Maybe 
problems with quotes and spaces in the path name, combined with a customized 
tex command? Liyu, it'd be useful if you shared the additional debugging info 
that Ikumi suggested

> - The path name of directory where aa.tex is saved
> - The type and year of your TeX distribution
> - Whatever you think might be clue to resolve this issue

Cheers,
