itcl 3.2 used TEA1 (which was SC_* macros).  The itcl in CVS
uses TEA2 (which is TEA_* macros, but unversioned).  You should
see that the tcl/tclconfig (and related tcl/sampleextension)
is TEA3 - it includes a specific TEA_INIT([<VERSION>]) in it
(to alleviate more version confusion in the future).

It's all the comments in the sample extension and in the macros
at this point unfortunately.  If you've used TEA before, then
it should be easy to move over.  One of these years I'll get
some time to document this better, but that's not going to
happen soon.  :/
