I use Linux Mint based on Ubuntu, so it makes sense for me to unpack the 
build bundle to see what custom patches they use.

I actually managed to get it to build with a couple of line changes.
I think there was some deprecated functionality in libpng that has now 
been properly removed.
The two offending lines were referencing elements of a structure that is 
now opaque.
I could create a branch for xsane updates if you like with the changes 
so far, but I will refer back to build for my distro to see what they 
did to make it work.

There are also a *lot* of compiler warnings regarding ignored function 
returns.
I don't know how critical they are but they make me nervous.
I will look into them also.

Cheers,
Ralph
