+Subject: fix getservby*_r result pointer value on error
+
+this is a clone of the fix to the gethostby*_r functions in
+commit fe82bb9b921be34370e6b71a1c6f062c20999ae0. the man pages
+document that the getservby*_r functions set this pointer to
+NULL if there was an error or if no record was found.
