+ * - Add DNS retries for Solaris and other systems
+ * whose gethostbyname_r version takes five arguments.
+ * - Move maximum number of DNS retries into a macro.
+ *
+ * Revision 1.41 2006/11/13 19:05:51 fabiankeil
+ * Make pthread mutex locking more generic. Instead of
+ * checking for OSX and OpenBSD, check for FEATURE_PTHREAD
+ * and use mutex locking unless there is an _r function
+ * available. Better safe than sorry.
+ *
+ * Fixes "./configure --disable-pthread" and should result
+ * in less threading-related problems on pthread-using platforms,
+ * but it still doesn't fix BR#1122404.
+ *
+ * Revision 1.40 2006/09/02 15:36:42 fabiankeil
+ * Follow the OpenBSD port's lead and protect the resolve
+ * functions on OpenBSD as well.
