Hi Harry,

to be honest, I have no idea. The package is automatically built when
you install it and I've not looked at the compile output. It seems to
work. 

Note that there are at least three packages called folding.el. The one
use is an old one that has ben around for a while (last update I think
was in 2004). There were other versions that attempted to update how
the package owrked using 'newer' emacs features. 

I'll try to look and see what version info I can find in the source
file.

Not sure how many of those 'warnings' are a real issue. The ones about
obsolete versions of functions can be ignored. The ones concerning wrong
number of arguments may be a concern.
