Trying to build it on post-8.2-pre-9.0 Mandrake system with
autoconf-2.13 resulted in

Making all in src
make[1]: Entering directory `/wrk/rpm/BUILD/syslog-ng-1.5.23/src'
cd /wrk/rpm/BUILD/syslog-ng-1.5.23 && autoheader
/usr/bin/autoheader-2.13: Symbol `HAVE_RES_INIT' is not covered by
/usr/share/autoconf/acconfig.h ./acconfig.h

FWIW the following patch seems to have fixed it:
