scm (5d9-4.1) unstable; urgency=high * Non-maintainer upload. * High-urgency upload for sarge-targetted RC bugfix. * Revert upstream "CAUTIOUS" define, which causes the scm build to fail its test suite on alpha (and, it appears, powerpc as well).

(lintian) scm (5d9-3) unstable; urgency=low * Properly clean up info files. * Make and install Xlibscm.info. scm (5d9-2) unstable; urgency=low * Fix path problem in slibcat. Hack at mklibcat.scm. (Closes: #241510) scm (5d9-1) unstable; urgency=low * New upstream release * Merge NMU sparc changes (Closes: #191171, #191356) * SHORT_INT is defined for ia64 upstream (Closes: #141928) * Scheme imps now grouped in info file (has been for a while) (Closes: #115452)
