IMHO, what we should do is : - Getting these png flags forced to yes when localpng is on as Ian does, this implies that we figure out why one of it has been forced to no in configure.in when localpng is set to yes, because it may hide some trouble (?). Anyway, testing will help. - We should not force this flags when using a system lib. Al is right that it seems to work for long in fltk2 without checking that flags, but ; unless it is obsoleted by the PNG team itself, we should care about these flags. I.e. It could happen that they decide to use it differently in future lib implementations. If some problems are encountered (as for now apparently) to make it get the correct value despite the settings in configure.in, then we can force it as a compromise, but I can eventually help then on this point if needed as I feel quite confortable with them now since the cairo addon ;-)
