Package: chemtool Version: 1.6.14-1 Usertags: goto-cc During a rebuild of all packages in a clean sid chroot (and cowbuilder+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.

Yet adjusting the declaration will ensure that the compiler can generate meaningful warnings. Best, Michael
