OK; apparently this is function is optional (it only exists if libpng
was compiled with PNG_INFO_IMAGE_SUPPORTED defined. I'll check for
png_read_image (which is actually used by r.in.png) instead.

I'm about to commit a new version of configure[.in] which fixes all of
the aforementioned problems.

Thanks Glynn,

Can you please let me know when I can check it out?

Will I have to re-build everything and start out with a "make distclean", or will I be able to just run configure and then build the PNGDriver?

Thanks again,

Thanks Glynn,

It's ready; if I say "about to commit", it will probably be done
within a few minutes of the email being sent.

Will I have to re-build everything and start out with a "make
distclean", or will I be able to just run configure and then build the
PNGDriver?

It should suffice to run configure then build PNGdriver.
