Package: fakechroot Version: 2.17.2-1 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.

The above inconsistency of types is caused by a mix of macros being in place:
http://sources.debian.net/src/fakechroot/2.17.2-1/src/fts.c?hl=34#L34
http://sources.debian.net/src/fakechroot/2.17.2-1/src/__lxstat.c?hl=26#L26
Likely these should all be sorted out via the common config.h rather than
risking those inconsistencies.
Best,
