obsolete files

That's true.  But instead of all those obsolete configure.bat files, a
single configure.bat in the top-level directory should be added to the
distribution.  Without this, configuring and building Binutils with
DJGPP tools is not for the faint of heart.

As a matter of fact, I don't understand wasn't top-level configure.bat
added to the current sources, since this is the only change that
Robert Hoehne needed to do to build 2.8.1 with DJGPP that wasn't
checked into the development sources.  All the other changes are
already there in v2.9.1.  Why?
