Sure.  I don't have a strong opinion on that one.

Better just try to use the feature and detect when it's not available.
E.g. check the feature's presence via `fboundp' or by trying the call
with the extra parametwer and catch the

I understand.  It's OK if the tests can't be run as-is.

No, please use the latest CVS version.  It's not like it's hard to get
from the browse-cvs area.
