[GRASS5] 64-bit PVF patch (read-only)

If anyone was holding his breath waiting for this patch, you
can exhale now. I have a tarball on my webpage at
http://www.grasshoppernet.com/~bhughes that contains enough
code to allow Alpha-platform machines to read the Portable
Vector Format. I do not recommend it as a general-use patch.
It "ought to work" on non-Alpha machines, but that's easy to
say and harder to prove. Apply to 5.0beta6d source.
Using this patch will disable access to the native-sized
pseudo-version-4 vector files that Alphans have been using, so
if you _need_ this you should continue using the PORT_LONG=8
hack. (and why are you using an Alpha in production???)
I have successfully drawn several of the vector maps in the
Spearfish examples, just to see what the rest of you have been
working on. I expect that there are still bugs. There is PVF
writing code in this patch, but it has not been tested.
This patch is an interim fix for a 64-bit architecture
until somebody does the job properly. This re-write has given
me valuable insight, and this code is not part of The Plan.
Bug reports are welcome, or something-
