obsolete directories in src tree: mmalloc, iwidgets, blt

Overseers,

While looking through the source tree for uses of old (pre
2.5) autoconf
I have found 3 directories that appear to no longer be used;
mmalloc,
iwidgets, and blt.  I was wondering if we should delete
these
directories.

I checked with the insight list (see
http://sources.redhat.com/ml/insight/2006-q1/msg00111.
html) about blt
and iwidgets and they seem to be ameniable to removing blt
and iwidgets.
blt was never used by insight.  iwidgets might have been
used, but if it
was it was five or so years ago.  I looked at some of the
files under
both blt and iwidgets and there are no insight or gdb tags
on any of the
files.

My understanding is that mmalloc is also no longer used but
it does have
a lot of gdb tags on the files and it has been in use more
recently.  At
the top level ChangeLog I find:

2005-02-08  Andrew Cagney  <cagneygnu.org>

        * MAINTAINERS: Delete reference to dejagnu/ and
mmalloc/ from the
        gdb/ section.  Update GDB's URL.

So I think that is when mmalloc stopped being used.  The
dejagnu
directory seems to have already been removed but the mmalloc
directory
is still there.

So, should these three directories (blt, iwidgets, mmalloc)
be deleted?

My main interest is to be able to tell the GCC list that we
can update
libtool because everything in the GCC and src trees is now
using
autoconf 2.5 or later.  So if we want to leave these
directories alone,
with the knowledge that they are no longer used, that would
probably be
good enough for my purposes.  But if they are no longer
used, maybe we
should just remove them.

blt was used at one stage by sid.  You might like to check
if that's
still true.  We were using some of the specialised widgets
in blt in
some of the visual components.

Binutils does not use any of these, so their removal is fine
by us.

Thanks for the pointer.  I sent email to the sid email list
and got a
reply that removal of blt would be OK with them.

It stopped being used long before.  It continued to be
checked out and
shipped until around then.

I think yes.
