Hi Ralf,
I noticed that.  It's not overwritten.  The old version had a
different name, xpm4.dll, or similar.

Do you mean http://gnuwin32.sourceforge.net/packages/libpng.htm ?  The
version there is 1.2.24 which seems to be older.  Under the assumption
that libpng13.dll is version 1.3, at least.  Can you provide a link to
a newer version?

Hmm, can anybody provide more information about the legal stuff?
AFAIK jpeg6b is included in so many programs that I doubt that there
are any problems.

I'm not a lawyer.  I simply assume that everything which is good for
Debian is also good for TeX Live.  The Debian guys are quite careful
about the legal stuff and I think I can rely on them.

I'm a bit more reluctant about GIF support.  AFAIK the patents expired
a few years ago and libungif circumvented them anyway.  But I'm quite
infamiliar with the legal stuff.  Is libungif in Debian?

If we provide libungif we certainly have to include the sources too.
All the other image libs are already in the TeX Live Build tree.  On
the other hand I don't think that GIF support is very important at all.
I personally have no problems not supporting GIF.

Yes, it will only work with web2c based distributions.  But do
non-web2c distributions provide manpages and info files at all?  Then
it would be sufficient to check whether kpsewhich is in PATH.
