For that particular function, I thought it was suppose to be exported
for use by applications.  It doesn't begin with underscores, and it
ends with "_r", so it certainly looked like it should.

These functions should be renamed if they are internal interfaces.

I'll remove gethostbyname_r.  If you find others that shouldn't be
there, please let me know.
