Tcl Source Code

2011-06-22  Andreas Kupries  <[email protected]>

	* library/platform/pkgIndex.tcl: Updated to platform 1.0.10. Added
	* library/platform/platform.tcl: handling of the DEB_HOST_MULTIARCH
	location change for libc.

2011-05-07  Miguel Sofer  <[email protected]>

	* generic/tclInt.h: fix USE_TCLALLOC so that it can be enabled
	* unix/Makefile.in: without editing the Makefile
