scm (5d9-5) unstable; urgency=low
* New maintainer. Adopted with permission of previous maintainer.
* repl.c (s_read): Remove static qualifier on declaration.

__x86_64__ just as with __ia64.
(Closes: #295074, #251765)
* debian/control (Build-Depends): Use libreadline5-dev in place of
libreadline4-dev. (Closes: #326297)
