	* tests/source.test

2012-02-23  Donal K. Fellows  <[email protected]>

	* tests/reg.test (14.21-23): Add tests relating to bug 1115587. Actual
	bug is characterised by test marked with 'knownBug'.

2012-02-17  Jan Nijtmans  <[email protected]>

	* generic/tclIOUtil.c: [Bug 2233954]: AIX: compile error
	* unix/tclUnixPort.h:

2012-02-15  Donal K. Fellows  <[email protected]>

	* generic/tclCompCmds.c (TclCompileDictForCmd): [Bug 3487626]: Fix
	crash in compilation of [dict for] when its implementation command is
	used directly rather than through the ensemble.

2012-02-09  Don Porter  <[email protected]>

	* generic/tclStringObj.c:	[Bug 3484402]: Correct Off-By-One
	error appending unicode. Thanks to Poor Yorick. Also corrected test
	for when growth is needed.

2012-02-06  Don Porter  <[email protected]>

	* generic/tclCompCmds.c: [Bug 3485022]: TclCompileEnsemble() avoid
