commit 747f31854a572b3dd64912997dde2dc984b1f2d8 Author: Yaakov Selkowitz <yselkowi at redhat dot com> Date: Tue Sep 26 20:36:35 2017 -0500 cygwin: fix gethostbyaddr argument types The first argument of gethostbyaddr needs to accept a generic pointer to be compatible with e.g. struct in_addr *. This caused an issue compiling krb5-1.15.
