Package: gnumeric Version: 1.12.15-1 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.

Hence all that is needed here is fixing the declaration for pln.c in order to enable the compiler to provide meaningful diagnostics in case of actual problems. Best, Michael
