It has some fallback logic for them, but doesn't "officially" want to
support them - which I think is understandable, as it would need to
handle separate aperture files then (and probably need much more
guesswork about the actual format as well).

Yes, I know.

Never trust an operating system you don't have sources for. ;-)

a question: gerbv can open old style Gerber?
On web site is clearly sayd NO?! so I never tried.
But sometimes from an old floppy disk come out some unreadable files by 
current softwares. gerbv can?

gvp files are marked at the start so should be very easy to recognize them

thank you again,
Valerio

As long as your zlib does so, it would be no problem.

I wouldn't want to deal with multiple compression interfaces.

:-)

And if you find a gerbv project file in there, please load that too.

(And, since you'll need functions to find out which files are gerbers,
those functions could be applied to commandline argument, to detect
project files without the -p that I often forget to type?)
