GMP page poits to gmp-5.1.2. After download I see in the README:
GNU MP is free software and may be freely copied on the terms contained in the
files COPYING.LIB and COPYING (most of GNU MP is under the former, some under
the latter).
Checking separate files I see that demos, tests and parts of build
machinery use GPL, the actual library seem to use LGPL. I admit
that for me such mixture does not look nice, but when comes to actual
use it seem to have no real impact on ECL. IANAL.
