Yes I understand 32-bit and 64-bit Vector Files are NOT yet
interchangeable and hence I followed the recommended proceedure of
converting to/from ASCII!

Although I have enough tools so Beta 11 compiles reasonably well under Dec
UNIX, I still have troubles with v.to.rast refusing to run (with its
warning about the data being 64-bit) and v.support NOT being able to
effect the corrections to v.to.rast's liking!  Whether it is my tools or
GRASS5 NOT being well supported under Dec UNIX, those are the type of
questions I am trying to address.  If GRASS5 has fuller support under
Alpha/Linux, that is good to know!
