[Michael Tautschnig]

Package: freebsd-libs
Version: 10.0-6
Severity: serious
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.

The full build log is attached; please do let me know if the problem is
unreproducible, in which case I shall try to investigate further.

reassign 759249 libbsd-dev, src:freebsd-glue
found 759249 libbsd/0.7.0
affects 759249 src:freebsd-glue
affects 759249 src:freebsd-libs
affects 759249 src:kfreebsd-10
thanks

Hi Guillem,

libbsd/0.7.0 caused this regression building freebsd-libs and possibly
kfreebsd-10 as well. Could you give some advice please?

Should we drop funopen etc. from freebsd-glue's stdio.h now that libbsd
provides them? Or would that create other issues? Thanks.
