[PATCH] Better way to check for getaddrinfo function.

Just thought that the following patch might improve checking for
getaddrinfo function (in configure.in)
I was forced to write 'coz getaddrinfo went unnoticed in Tru64 Unix.

(displaying attached patch)

$ diff -r configure.in configure.in.1
920c920,944

function])
