Well, even if you got pnmtopng to compile (which should be possible,
Windows is explicitly mentioned as supported on Netpbm's project
page), you'd still be faced with the problem to get doxygen for

That's not very much. ;-)  Netpbm comes with about 150 conversion

See Ted's reply.  Btw., we'd need to keep redundant copies of the
files in CVS if we did this (one JPEG and one PNG for each source

not too difficult to resolve the CVS conflict when Ted and i started
to edit these files simultaneously...
