* e-host-utils.c (e_gethostbyname_r)
[HAVE_GETHOSTBYNAME_R && GETHOSTBYNAME_R_FIVE_ARGS]: Set `*herr'
to zero if the function returns a non-NULL pointer to the hostent.
According to the docs, a returned non-NULL hostent always means
"no error" no matter what the returned value of `herr' is. [And
in fact, at least on libc 2.2.3, trying to resolve `localhost'
sets herr to `HOST_NOT_FOUND' even if the name is resolved
correctly and the returned hostent is non-NULL.]
