As I introduced the package a few years ago, I was wondering if we had a
way to measure the usage of this package and think about removing it.
Then I checked with the guardians of the temple aka debian and found
that the maintainer probably fixed the gcc 10 issue:

| dieharder (3.31.1.2-1) unstable; urgency=medium
|
|   * New upstream minor release accomodating gcc-10 and its treatment of
|     multiple definitions of global variables		(Closes: #957134)
|
|   * Based on new 'upstream' git repo at github.com/eddelbuettel/dieharder
|     which spawned off the salsa.debian.org repo for this package
|
|  -- Dirk Eddelbuettel <edd at debian.org>  Sat, 25 Jul 2020 12:36:49 -0500

This would not be the first time that debian extended the life of
unmaintained upstream.

What do you think ?
