My understanding was that FSF approval was needed for relicensing code 
from other FSF-owned packages (as opposed to correcting simple mistakes, 
e.g. making the license notice on a file reflect established licensing 
practice for files used in a particular way).  (E.g., when license 
exception notices were added to soft-fp for use in libgcc, that involved 
FSF approval for adding those notices.)

I suspect other architectures might benefit from changes made in GMP to 
improve performance - but certainly this is code that has diverged 
significantly from the GMP versions over time.
