Correction: It becomes incompatible with LGPL v3, not GPL v3.

The license of a combined binary becomes the lowest common denominator,
i.e. that of the most restrictive part. If one file is LGPL v2.1 and
you combine it with 1000 LGPL v2.1 or later files, the or later clause
is void as long as that one file is used.
May I politely and respectfully suggest that you sit down for a short
moment and read the text of the LGPL 2.1? During this email exchange
and yesterday's IRC conversation it has become clear that you are not
fully aware of its terms (paragraph 3 seemed to be a surprise to you
for example). Even the release of GPL v3 had escaped your notice almost
a year after the fact and more than two years after the draft process
Discussing these issues without a full overview over the facts will only
lead to misunderstandings and flames, not to mention conclusions drawn
from incomplete or false assumptions.
Now please take these remarks in the constructive spirit they were
written and consider things with a cool head.
