Tcl Source Code

2011-04-04  Donal K. Fellows  <[email protected]>

	* generic/tclCmdAH.c, generic/tclCmdIL.c: More generation of error
	codes (miscellaneous commands mostly already handled).

2011-04-04  Don Porter  <[email protected]>

	* README:	Updated README files, repairing broken URLs and
	* macosx/README:	removing other bits that were clearly wrong.
	* unix/README:	Still could use more eyeballs on the detailed build
	* win/README:	advice on various plaforms. [Bug 3202030]
