+ * generic/tclInt.h: New utility routines:
+ * generic/tclParse.c: TclIsSpaceProc() and
+ * generic/tclUtil.c: TclCountSpaceRuns()
+
+ * generic/tclCmdMZ.c: Use new routines to replace calls to
+ * generic/tclListObj.c: isspace() and their /* INTL */ risk.
+ * generic/tclStrToD.c:
+
* generic/tclStringObj.c: Improved reaction to out of memory.
+2011-03-16 Jan Nijtmans <nijtmans@users.sf.net>
+
+ * unix/tcl.m4: Make SHLIB_LD_LIBS='${LIBS}' the default and
+ * unix/configure: set to "" on per-platform necessary basis.
+ Backported from TEA, but kept all original platform code which was
+ removed from TEA.

+2011-03-14 Kevin B. Kenny <kennykb@acm.org>
+
+ * tools/tclZIC.tcl (onDayOfMonth): Allow for leading zeroes
+ in month and day so that tzdata2011d parses correctly.
