Honestly, if this patch fits you, I would merge it as is. This issue is already
a corner case, but as it's hidden inside windres code and because of
the existence of the "Program Files" folder can be problematic.
The other has to be triggered by someone explicitly passing "--preprocessor"
with an unusual path. So honestly I don't think it would ever happen.

Agreed.
