So we hope that there is still a chance to make GRASS the only one
to suppor this :)

Note that v.buffer is somewhat in transition:
"All these test cases are successfully completed by v.buffer/v.parallel;
on confirmation by I would reactivate v.buffer/v.parallel and deactivate
v.buffer2/v.parallel. For trunk that would mean that v.buffer which is
actually v.buffer2 gets replaced with v.buffer, same for v.parallel.

If you can compile yourself, please try GRASS 6.5 from current SVN
(or weekly snapshot) and go into
and compile this fixed older but apparently better version.

If that then works ok for you, it will be another reason to reactivate
the fixed original version of v.buffer rather than promoting the
currently used v.buffer2.
