+	* unix/configure.in:
+	* unix/tcl.m4: added support for AIX-5.
+
+	* generic/tclIO.c (Tcl_NotifyChannel): removed #ifdef around code
+	for old channel structures, placed preserve/release around statePtr
+	* generic/tclIO.c (CloseChannel): the statePtr for a channel was
+	not being freed when the last channel in a stack was freed,
+	causing a mem leak.
+
+	* unix/tclUnixChan.c: updated channel types to strict
+	TCL_CHANNEL_VERSION_2 style to avoid compiler warnings.  They work
+	either way, but this avoids compiler warnings (that worries people).
