These are bugs in the configure.ac file of the zebra package: the header
check needs to ensure some necessary headers are included beforehand.
Please report them to its maintainer, and point him to the Autoconf
manual at

http://www.gnu.org/software/autoconf/manual/html_node/Present-But-Cannot-Be-Compiled.html
http://www.gnu.org/software/autoconf/manual/html_node/Header-Portability.html

(and hinting that a new Autoconf version is available may be useful, too
:-)

Cheers,
Ralf
