Thanks for the info. This indicates that m4/getaddrinfo.m4 requires some surgery, and that my simple patch was wrong. getaddrinfo.m4 currently does not find the OSF/1 5.1 getaddrinfo, since it doesn't include <netdb.h>. I'd have some qualms about writing this code myself; I hope Simon can take a look at it.
