I think PNG_DLL_EXPORT is not intended to be used directly.
I am not sure what problem this causes but it is just the way this
library is written ...

Thanks Philip.
The whole thing with PNG_DLL_EXPORT not being defined in png.h or
png.c is still confusing to me
(pngpriv defines it), especially since png.h ends up using it
post-pre-processing, but I don't know if
that would bother people outside the minority that inspect the
pre-processed code.
I'll leave this here as a thought for any committer bothered by this,
though I won't be pushing it.
---- png.h ----
+ #ifndef PNG_DLL_EXPORT
+ #define PNG_DLL_EXPORT
+ #endif
