Would you care to enlighten me what this "original license" might be?
The files themselves contain no information about it.

This is not about the files you refer to. The reference in those files
was obiously wrong until your patch was merged. (I admit that's a +1
for your patch).

This is about the files that have *no license header*. We *must* assume
that they are covered by a central license file in the top directory.
If we don't do that, it'd be questionable if said files are
distributable at all. Legally, they'd probably not be considered FLOSS.
Files without explicit copyright are be covered by regular copyright
law, meaning that copying and redistribution are _not_ allowed under
most legislations.

I hope that makes it clear why we need to be firm that these files are
covered by the top license file. That central license file used to be
COPYING. The point of my post was that we have *two* such files now,
and without resorting to history it's impossible to tell which file is
covered by which license (and even with history it's hard, but that's
another posting).

Historically, these files were added to the tree by Christophe, and
he'd copied the LGPLv2.0 text into COPYING, thus it seems likely that
he meant them to be under LGPLv2.0.
