With apologies to the OP, that makes a pretty big difference to me as
21.4 is just about EOL and Mule-UCS deprecated in favor of 21.5 for
us. I'll try to have an update by the weekend.
Ouch. The version of libpng I have in my -I path is v1.6, and our
code tries to access declared but not defined structs (as of v1.5).
For this bug I'll work around by configuring --without-png.
However, I think we should backport

* glyphs-eimage.c (png_instantiate):
Update the PNG handling code to work with versions of the library
where the png_info structure is no longer visible. Thank you for
the report, Robert Delius Royar.
from 21.5.
Vin, any objections? Note that the libpng docs claim that the
relevant "png_get_*" and "png_set_*" functions have been available
since libpng v1.0 or so, and I would imagine that by now pretty much
everybody has libpng v1.2.
Steve, I suppose SXEmacs updated PNG code for v1.5 long ago?
