Package: gdb
Version: 7.2-1
Severity: important
Tags: patch
User: debian-h...@lists.debian.org
Usertags: hurd
Attached please find a small patch for gdb to work properly under
GNU/Hurd. It can safely be added last to the series file.
The last two parts of the patch (finding and linking with libhurduser
and libmachuser) will not be needed in next version of libc0.3, where
they will be integrated into libc itself (according to Samuel Thibault).
This bug is related to bug #579834 which will be merged when this bug
report is registered.
Thank you for your attention.
