enable-pngsupport bug
Created by: LiaoHuaping
My project exist libpng 1.6 version. I try to config --enable-pngsupport to enable png suppport. But it's no work, is report "checking for png_check_sig in -lpng... no". And i try to use old libpng of version 1.2.37, it's success. I think there are some problem to use libpng new version.
