This is the first configure failure I can remember. On Solaris 2.5.1, PNG 1.0.2, png.h says: #define PNG_LIBPNG_VER 10002 /* 1.0.2 */ ./configure gives: checking for pow... yes checking for png.h... yes checking for png_read_image in -lpng... yes checking for workable png version information... no checking for tiffio.h... yes Corsican correctly detected this same PNG. I don't see why I'm not getting this message from configure.h: *** WARNING *** $png_problem I'm not touching that with a 10-foot pole! If you really want to use the installed version of libPNG, rerun configure and add '--with-png=yes', but don't blame me if XEmacs crashes!" Jareth, it looks like you recently patched PNG detection - let me know what further info you need. greg
