While similar they are different. My understanding is this:

**	tdbc is a bundled package. It is maintained externally, and
	we distribute it only. Therefore  pkgs/

**	The zlib sources are 'only' a fallback to use when no usable
	system zlib library was found, or if explicitly requested (static
	linking). Therefore compat/, where we have other fallback files,
	mainly headers.

**	And libtomath is an integral part of the core. We use only the
	sources coming with Tcl, never look for a system library, and,
	most important I believe, we have AFAIK forked the sources. IIRC
	Kevin said something to the effect that our libtommath contains
	a number of changes which are not in the original libtommath.
	IIRC the changes were given to the upstream maintainer, but
	rejected.
