+	* ccache.h: added windows INTERFACE keyword to all functions.
+        * encryption.h: more segment games for the PC--added NEAR to three
+           external data objects.
+        * wordsize.h: added constants VALID_INT_BTIS and VALID_UINT_BITS for
+           detecting overflow when casting a long to an int.
+        * k5-config.h: numerous PC changes such as adding NEED_LOWLEVEL_IO
+           which enables the read/write level of I/O.
+        * Makefile.in: osconf.h now pulled in from stock/osconf.win.
