Severity: important

Usertags: hurd
Hello,
Currently libdrm FTBFS on GNU/Hurd due to a missing case in
include/drm/drm.h. Attached is a patch, hurd-port.diff, to fix this and
fixes for PATH_MAX issues in in xf86dri.c and include+defines for GNU
in xf86dri.h.
Additionally the patches debian_rules.diff and debian_control.diff adds
Hurd to the architecture list.
Thanks!
