Yeah, understood. That script *does* build a symbols file with the
correct "first version" for each symbol, because that information is
there in text form in the changelog at the top of openconnect.h

It basically builds a file which is the same as the one you're doing by
hand, although you ought to be marking the @OPENCONNECT_PRIVATE symbols
as *new* in each release because they have no ABI guarantee; they
shouldn't be considered the same as the same named symbol in 6.0 as
your symbols file suggests.

Especially if you mark those symbols as being compatible with v6.0 :)

Agreed.
