The Free Software Foundation have just been of great assistance in
sorting this issue out.
In an email to us, they have pointed out a very embarrassing omission.
In fact the MPIR 1.2.2 tarball is missing the LGPL v3 license text.
The GPL v3 text is there, but not the LGPL v3 text. Fortunately it is
in the other "past" tarballs. This is my responsibility, as I updated
the tarballs (some time late last year) when made aware of the issue
with mpf/set_str.c.
I am very embarrassed about this and apologise to all involved!
The FSF also gave us some guidance on how we can word the statements
on our website to make it clearer to our users that the overall
license of those past libraries is LGPL v3+. I will also update the
website along the lines of what they suggest.
I want to take this opportunity to publicly thank their Licensing
Compliance Engineer for the very helpful response!
Bill.
