It's the LLGPL which prevents taking LLGPL code and relicensing under
the more liberal BSD license.

I'd say at the time of the fork, the license of UFFI was interminate
between BSD and LLGPL since both license texts were present. However,
it's fairly easy to take BSD licensed code and add a LLGPL license to
it. It's not possible to do the opposite.

Very good. I'll complete the transition from LLGPL to BSD in the UFFI
source code. Given my intent (and preconception) was that UFFI was
completely licensed under BSD at the time of the fork and that I'm the
copyright holder, you can safely convert your source file license text
to BSD.

Best,
