Package: kstart Version: 4.1-3 Severity: minor 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.

This type conflict is caused by the use of _XOPEN_SOURCE rather than using
#include <config.h>, which would define _GNU_SOURCE, in tests/tap/basic.c:
http://sources.debian.net/src/kstart/4.1-3/tests/tap/basic.c?hl=39#L39
Compare to tests/kafs/basic.c:
http://sources.debian.net/src/kstart/4.1-3/tests/kafs/basic.c
Using #include <config.h> consistently as first include will ensure this kind of
inconsistency.
Best,
Michael
