In GNU Emacs 21.1.2 (i686-pc-linux-gnu, X toolkit)
of 2002-03-15 on a8.complang.tuwien.ac.at
configured using `configure --prefix /usr/local --without-toolkit-scroll-bars'
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
in 20.7.2 (mapconcat 'identity '(1 10) ", ") yielded "1, 10"
but in 21.1.2 this gives an error

This is not an undocumented change in mapconcat, but rather a
documented change in concat. See the NEWS file:
** Code that uses `concat' with integer args now gets an error, as
long promised.
The solution, of course, is to use
(mapconcat 'int-to-string '(1 10) ", ")

`concat' does not stringize integers any more, this has been deprecated
for a long time already. Use number-to-string as the map function.
