+       Publish GCC-8.2.0 package set on OSDN.net
+
+       * mingw32/mingw32-gcc4.xml (download-host): Relocate to osdn.net
+       (package-group-hierarchy): Remove now-redundant "GCC Upgrade Blockers"
+       (gcc-lic, gcc-core-bin, gcc-info, gcc-man, gcc-lang, libgcc-dll-1)
+       (gcc-ada-bin, libgnat-dll, gcc-c++-bin, gcc-c++-man, libstdc++-dll-6)
+       (gcc-fortran-bin, gcc-fortran-info, gcc-fortran-man, libgfortran-dll)
+       (gcc-objc-bin, libobjc-dll-4, libatomic-dll-1, libgomp-dll-1)
+       (libssp-dll-1, libquadmath-dll-0, libquadmath-info): Add release
+       references for version 8.2.0-2 package set, and also for previously
+       unmanaged version 8.2.0-1 and version 7.3.0-1 package sets.  Delete
+       references to all earlier version package sets; associated packages
+       will remain on SourceForge.net, but are not scheduled for relocation,
+       and will not be accessible through the OSDN.net download service.
+       (gcc-core-dev, gcc-ada-dev, gcc-c++-dev, gcc-fortran-dev)
+       (gcc-objc-dev): Add release reference for version 4.8.2-2, and delete
+       all other version references.  This is a virtual package, and thus is
+       effectively empty; it serves only to clear out aberrant content which
+       may have been inherited from a prior version 4.8.1 installation.
+       (gcc-core-doc, gcc-c++-doc, gcc-fortran-doc): Likewise, but identify
+       the sole residual virtual release as version 4.8.1-5
+       * common/issue.log mingw32/issue.log: Update accordingly.
