Most likely, your changes to libdecnumber will give it GPLv2+ licensing,
since the library is already available under GPLv3+ and you would just
be widening that to also include GPLv2 (in other words, your change
would implicitly be GPLv2+ because it already has the "or later" built
in by the fact that the library is already available under a later
license). But if you were to succeed at releasing libdecnumber as
GPLv2-only instead of GPLv2+ (I don't recommend attempting that, but for
the sake of argument), then you would modify that part of the LICENSE
file statement to add libdecnumber to the set of files which come from
GPLv2-only sources.
