 Formerly, I was not able to build PNG images due to a bug in pnmtopng
provided in the linux distribution RedHat 5.2

But I got a source (suppoedly recent, from suse) which I finally
succeeded to compile, so that is yields an image, instead of crashing.

The new problem is that the PNG has a gray background, while the GIF is
transparent. Of course I use the same pstoimg routine, just changing the
configuration file (99.2 revision 1.29)

==> Is that grey background with PNG a bug, or a "feature"?
