Compiling BIND 9.9.5 on OpenBSD

while compiling BIND 9 Version 9.9.5 on OpenBSD, I've got

making all in /usr/src/bind-9.9.5/lib/lwres/unix/include/lwres

adding

#ifdef HAVE_INTTYPES_H
#include <inttypes.h> /* uintptr_t */
#endif

to the file <bind9-source>/lib/lwres/gethost.c fixes this issue (type "uintptr\_t" not known). This issue has been reported upstream to ISC and will be fixed in the next BIND 9 release.
