Tcl Source Code

2011-08-30  Jan Nijtmans  <[email protected]>

	* unix/tcl.m4:    Make SHLIB_LD_LIBS='${LIBS}' the default and
	* unix/configure: set to "" on per-platform necessary basis.
	Add Haiku support and better NetBSD/FreeBSD support.
	All of this backported from TEA resp. Tcl8.5, but kept all
	original platform code which was removed from TEA.

2011-08-22  Andreas Kupries  <[email protected]>

	* win/tclWinDde.c (Tcl_DdeObjCmd): Fixed use of the C99 feature
	(Variable declaration within statement block) rejected by
	MSVC6. Moved the declaration to the beginning of the block.
