Package: dealer Version: 0.20040530-4 Usertags: goto-cc During a rebuild of all Debian packages in a clean sid chroot (using cowbuilder and pbuilder) the build failed with the following error. Please note that we use our research compiler tool-chain (using tools from the cbmc package), which permits extended reporting on type inconsistencies at link time.

Adjusting the declaration in defs.y should fix these problems, assuming no truncation can occur. Best, Michael
