Configury like this just hasn't been merged back into GCC.   The version 
number in GCC is mostly irrelevant as GCC doesn't install libffi; it is 
simply incorporated in its entirety into libgcj.   Ideally the configury 
should be merged, but as you've no doubt discovered, this isn't a simple 
task.  If you think we should update selected parts of the configury in 
GCC then I can do that.

ChangeLog.libgcj goes back to when libffi was first packaged with 
libgcj.   It shouldn't be used anymore.   See gcc/zlib/ChangeLog.gcj for 
something similar.

ChangeLog.libffi are changes that have been made manually to libffi 
outside of the GCC tree.  It's reasonable to delete entries from 
ChangeLog.libffi as they are committed to GCC and merged back into libffi.
