Import Debian changes 5d2-3debian/5d2-3

scm (5d2-3) unstable frozen; urgency=low

  * Fix libncurses4-dev -> libncurses5-dev build depend (Closes: #58435)
  * Fix libreadline2-dev -> libreadline4-dev build depend.
  * Fix license location in copyright file (lintian warning)
  * Add tetex-bin as a build depend (needs makeinfo) (Closes: #53197)
  * Add -isp option to dpkg-gencontrol (lintian error)
  * Move scm to section interpreters.

scm (5d2-2) unstable; urgency=low

  * Apply patch from upstream for bug in eval.c. (Picked up from
    comp.lang.scheme)
  * Add Build-Depends on slib, librx1g-dev, libncurses4-dev, libreadlineg2-dev.
  * Up standards version.
  * Correct description: this is an R5RS implementation now
  * Make sure no optimizations are done on m68k. (Closes: #52434)

scm (5d2-1) unstable; urgency=low

  * New upstream.

scm (5d1-2) unstable; urgency=low

  * Remove TAGS on clean (cut the diff back down to reasonable size).

scm (5d1-1) unstable; urgency=low

  * New upstream.
  * move stuff to /usr/share.

scm (5d0-3) unstable; urgency=low

  * Change scmlit call to ./scmlit call (missed one) (Fixes bugs #37455
    and #35545)
  * Change man file permissions to 644 (fixes lintian warning)

scm (5d0-2) unstable; urgency=low

  * Changed copyright to reflect new source.

scm (5d0-1) unstable; urgency=low

  * New upstream.
