Hi, looking at an (overdue) update of print/ghostscript/gnu, I'd really like to get rid of the a4 flavor. It's stupid, device drivers testing for a cpp macro 'A4' are cleary wrong (because they can derive the paper size by other means), and I can't think of many people still using DEC LN03 or Xerox XES (featuring sixel graphics) or similar cruft (I saw some mentioning of hercules graphics somewhere in the code). People using a printer whose gs driver requires the paper size defined at compile time should probably just buy a new printer.
So, unless I see some real complaints, the a4 flavor will be removed. CIao, Kili
