Package: rdesktop Version: 1.7.1-1 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.

Looking at http://sources.debian.net/src/rdesktop/1.7.1-1/debian/patches/01_paging.dpatch?hl=32#L32 it seems both RD_BOOL and BOOL are being used here, which apparently expand to different types.
