There are two possible issues to consider with this patch: - should we add -std=c89 always? or add some test and decide based on results? where? - there seems to be always -std=gnu99, when we add -std=c89 there are two -std. it works because the later wins. is it ok? or how to remove -std=gnu99? The other possibility would be to remove '#define _POSIX_SOURCE 1' from: media/libpng/pngpriv.h
