Hi, all!
Here is a patch that checks for members of struct passwd by trying to
compile test programs rather than just egrepping pwd.h.
Yes, I know this is probably not a part of Hesiod that is shakey, but
I want to report it because it may cause problems in the future, and
it's nice to see what is happening when configure runs.
